I'll have to take a picture of where/how the harness comes from the block to the PCM... Picture in your mind, the engine - Side to side with the crank on the passenger side (left), the harness comes from the #5 cyl on the right, moves towards the radiator ish, then strait down. meets with the front most motor mount, goes under it, then (inside the wheel well) goes up, and into the bumper. Why the bumper you ask? because the PCM is behind the fog light :-/ yea, its behind the little reflector. -Justin

Sadily, I've gotten more input on here than on a actual chrysler forum :-/ http://www.chryslerforum.com/forum/chrysler-pacifica-15/missfiring-04-pac-18401/ -Justin

a Subaru guy. Telling another Subaru guy on a Subaru forum to Put a Toyo/Lexus engine in his chrysler. Sounds Legit. -Justin

yep, that is pretty much where i am at! They call me the "Frost Man" on the airwaves -Justin

Well, I checked the codes again and its throwing the 355 and 356 again :-/ debating on pulling the harness out again and double checking.. -Justin

Well.. I ripped that wire harness apart and found probably 7 or 8 wires that needed to be fixed.. I soldered and heat-shrunk them back new. I did get a C.E.L. again though (P0355). Hopefully the other codes dont return since a couple of those wires should've fixed a couple codes, one was a signal wire to coil #6.. Here's hoping! *prays to the car gods* *goes outside and provides a burnt offering* A few pictures.. -Justin

Yea, those are great inexpensive radio's. You can even buy them used for ~50 bucks depending. Cheap to Tweak & Peak too! -Justin

I don't know about that 'Lil 'Will.. I never had any good luck on it. I ran my Galaxy 959 barefoot on it with 17w and barely got 4 miles away - IF that (And yes, it was tuned). I got better range with the plain 'ole 4 ft white whip. You do get what you pay for though. For a Mag mount, I'd at least run a wilson 1k barefoot they are the best bang for your buck on range. I can get a good 25 miles barefoot on my predator 10k. LOT of skip out there now-a-days.. I've been talking to Florida, Rhode Island, Texas as well as New Jersey, I'm only running 125w to it. A "Decent" cheap CB is a Cobra 29ish. They have a built-in SWR calibration meter as well as some signal modification knobs. edit: "barefoot" means without any amplifier's. -Justin

Well, got the car back and the wife turned around and drove it back agian. I figured as much since it was a motor mount they said was to fix the problem - though, i saw the old one and i already knew it needed replacing. I popped the hood to look at the wire harness and, of course, there's plenty of slack. The biggest problem i have is the shop is the "dealer" shop for warranties and they were the only one that did PCM/ECU troubleshooting. Apparently, I P-O'd the shop because I called and ripped the guy a new one. eff this, eff that, get your effing car out of here... I did call back and apologize for doing that and worked the situation back down. I got the car back home and looked at the harness a bit and got the C.E.L. to go away, somehow.. it worked its way out. I'm thinking something wasn't fully "clicked" in when they installed the new PCM. edit: the new CEL was P0355 which is coil primary/secondary circuit for cyl 5. this is the same code I had (along with P0356 same code but for #6) when i took the car in in the first place ::facepalm:: -Justin

So.. I called the shop on Thursday, after i took the car back; after it took them a week to meter and trace wires and eventually (at first) find that it in fact was the PCM. Now they said that the problem is a Motor mount, is causing the wires to tug on the motor/frame and causing it to misfire? Does this sound legit? on tuesday i drove the car practically all the way home without a problem about 7 miles. Up and down hills, stop lights (from 58th and Garrison to Golden (Map link this was my actual route )) and didnt have a problem, then suddenly it threw a CEL at a stop light just off of simms and 8th?? Am i crazy? Any Input would be nice if you could. They are trying to stick me with a 250$ bill because the motor mount wasnt covered under the warranty and you know as much as I do how stinking easy (usually) to replace a mount. I call B.S. because I'm thinking the mount would've had to completly busted to cause the wires to tug because there should've been plenty of slack on the wires. Along with that, they should've found that problem a week and half ago when they were looking at the wires, tracing and such, and went "hey, this doesnt have a whole lot of slack" sorry for the rant.. I'm just trying to get a prospective on it. I tried an actual chrysler forum but sadily, a subaru forum has replied to this topic (see here) edit: I called Go Chrysler/Dodge's service dept. and the guy there even called B.S. on it. saying they are just throwing parts at it. -Justin

Welp, got the car back.. drove like a champ. Missfiring again. Dropped it back off :-/ -Justin

Well, I got news back from the shop.. it WAS the ECU/PCM. It IS under warranty, and through all the dinking around with the car, I only have to pay my 50$ "diagnosis" fee and not the other random BS that they tried to tack on just to diagnose it. The guy also mentioned that the Injectors for cyl 5 and 6 were "missfiring" as well. Which, to me, what are the odds that the 2 coil packs and the injectors are missfiring? Now, all I have to do is wait for the part to come in :-/. Hopefully it comes in today and it fixes the problem. -Justin

Probably OE---- OEM.. haha.. there's only 125k on it.. and as far as power, its running pretty strong. I did replace the battery with a larger one (closer to the right size mind you ) - simply because the battery that was in the car when i bought it was too small (about ~400CCA too small) charging system is good.. and the battery is brand new. I did, briefly look at wires to see if there was any chafed wires but didnt find too much. I am a little miffed about that.. I bought the car only 7 or 8 months ago at the most and if they think that I'm going to pay for (at least) half of this crap is BS. Its hard enough to make the monthly payment.. I'll just as soon as take the dam* car back and lump it in my bankruptcy. In hindsight, I should've waited a bit like i wanted to and then bought the Subaru they had on the lot a week or so later - at least I would've been able to work on it, or, at least, had some input on how to work on it.. -Justin

I'm afraid I didnt get too far with that.. I ohmed the C.O.P.'s and noticed they were slightly different than each other.. 3 at .78 and 3 at .3ish.. I ended up taking it into a shop because the ECU IS in fact under warranty but one of their shops have to do the repair. I dropped it off tuesday night, and after calling them today, they've apparently been banging their head on it too. They are thinking it to be some wiring gremlins. Uugh, it was 50$ to diag. (which is a load of BS because all they did is hook a ODBII reader to it and verify what i already left in my "what is it doing" section) and another 65 for them to remove the "plenum" to get to the southern 3 coil packs. Which, to me, is crap because a "diagnosis of the problem" should be - "hey, here's the problem, and here's how to fix it." Not, "hey, I plugged my reader into your car and it says there's crap wrong.. you want me to look to see what crap is wrong?" The sad part, is they are at the same place I was at before I dropped it off. ..... This is exactly why I do my own repairs. Just unfortunately, I was out of my league with books, knowledge and time to be able to completely diagnose this problem. One part that kinda scares me a bit is - Here is Chrysler's "fix" for the P0306 and missfiring codes: http://www.aa1car.com/library/misfire_chrysler.htm Which is a code I did get at one point. Luckily, I havent gotten that one again after i put some (very concentrated) seafoam in the gas. -Justin

Ok. So I'm banging my head on the concrete for this one. I have a P0356 ("F" Primary/Secondary Ignition circuit) and P0355 ("E" Primary/Secondary Ignition circuit) codes being thrown on my chrysler. Naturally, I replaced the spark plugs - installed NGK laser platinum (near OEM). and at one point it deliberatly said missfire on cyl 6. Now i only have those 2 codes. It has a coil on plug setup so i moved the #6 pack to #3 to see if the problem would move - It did not. I still have the same codes and it drives like bat crap. The hardest part is GETTING to the spark plugs.. I have to take apart most of the intake to get to it.. Ideas? I'd hate to say it but i was thinking PCM :-/ -Justin

look what i found! They let me have the entire hatch for 85$ - still loaded. Upull&pay wanted 80 for a stripped-down gate with just the glass so that was nice. took 20 min to take off, another 20 to put back on and switch the locks Its off a '98, and it has an lock actuator on it so I'm going to hook that up too! ;-) -Justin

Yea.. There was that too.. I guess the other real big problem is that he's spending mama and grandpas money. I got it running, did some understandable upgrades and to make mom happy so he can drive his car again. But! Since he's not funding this little project - no. -Justin

hmm.. neato! I didnt think of it that way. At any rate, I've already ordered it. Now, My new problem: Kid wants a "bigger" turbo, Instead of rebuilding or replacing the OEM, and a BOV. *shakes head*. Basically, hes going through ebay, checking the compatibility list and seeing that they all fit - Not realizing they arent all "Plug and play", or even what might need to go into "upgrading" just so the car will work with the new turbo.. -Justin

Just a little bit.. yea. sadily. -Justin

well, it boosts and boy doe it haul..... the mail. turns out, it was the MAF, thanks "rallynutdon". pulled it off and it was all kinds of black. Also, he was running 87 octane... :-/. Put 91 in it and that cleared it up almost immediately. I'm going to be putting a Turbo timer in it and a boost gauge tomorrow. I was talking with a buddy of mine, I still think it should have a bit more turbo pull. He thinks i'm crazy. We'll find out tomorrow if its boosting ~13ish lsbs. thanks everyone! -Justin

aaaannnnd now I have no bucking and no/late boost ????? I havent touched it, decided to take it for a spin to show someone what it was doing and had no bucking Car -Justin

..... Coil Pack. I just pulled and plugged the vacuum going to the waste gate. Had the boost - only amplified the bucking... oh, and to add. It starts up first crank and doesnt idle rough at all.. -Justin

oh, It'll still haul butt.. I bypassed the wastegate to leave it closed.. i had a LOT of boost. I put it back on, still have a bit. but it bucks right when its supposed to boost.. either senerio :-/ would a faulty coil over do it? -Justin

No CEL :-( I even plugged it in for giggles to be sure. Kinda odd.. i thought... -Justin

any idea on the bucking? -Justin
