mickytrus Posted December 5, 2013 Share Posted December 5, 2013 So the car idles fine. had a tune up new coil pack and runs bad.... no power..... feels retarded... or maybe the (Cat is clogged kind of feeling) It has less than 120K on it.... It spits back some codes... from what I was told the codes refer to misfire.... but everything ingnition wise is replaced....(meaning plugs,coil pak, wires, plugs) Some ideas would be nice... What to check and perhaps how to check.... Thanks, Micky Link to comment Share on other sites More sharing options...
upnorthguy Posted December 5, 2013 Share Posted December 5, 2013 I'm sure the gurus here will want specific codes for better troubleshooting. Link to comment Share on other sites More sharing options...
luko Posted December 6, 2013 Share Posted December 6, 2013 What did you use for a coil, wires and plugs? Subaru's are very finicky, always use OEM coils and wires, I found that Beck Arnley makes a good coil and wires for Subies and only use NGK plugs....I've made the mistake before and put on a non OEM coil and wires before and it burned my cat up Link to comment Share on other sites More sharing options...
mickytrus Posted December 9, 2013 Author Share Posted December 9, 2013 It has been a while Since I put it on... they could... may have been beck or standard..... Coilpacks NKG plugs..... So luko if burned up your Cat? What happened after the cat burned up? was the cat clogged? Ill get some more details.... go and look at the car....

travmo86 Posted December 10, 2013 Share Posted December 10, 2013 Suffering the same issues with a 93 legacy 2.2. I have a thread a little further down that has a few suggestions from members. Still have had no luck with mine yet. http://www.ultimatesubaru.org/forum/topic/142792-93-legacy-no-power-at-all-under-load-will-idle-ignition-relay/ Link to comment Share on other sites More sharing options...
luko Posted December 12, 2013 Share Posted December 12, 2013 It just burned the honeycomb out of it so the downstream oxygen sensor sensed that it wasn't doing it's job, so I just made a dummy o2 sensor to get the light to go out...it ran fine just the cat was burnt up and could not do it's job Link to comment Share on other sites More sharing options...
Fairtax4me Posted December 12, 2013 Share Posted December 12, 2013 Check timing belt. Cars 17 years old, the belt could have jumped a tooth or two. Link to comment Share on other sites More sharing options...
okamikai Posted December 12, 2013 Share Posted December 12, 2013 if idle is fine but if feels lacking power you should check the following: - Air Filter - Fuel Filter - Fuel Pressure - Check Brake Pads for uneven wear, this may be a sign of calipers sticking - Loose or Cracked vacuum hoses - If the Cat is burned up its definitely clogged and it will affect performance noticiable Link to comment Share on other sites More sharing options...
mickytrus Posted December 16, 2013 Author Share Posted December 16, 2013 Thanks all very good points taken... I got to spend some time yesterday.... I towed it out of the library and back to the owner's home.... So I get ther... I starts up just fine.... Then.... you step on gas pedallll... and it is like this: Boooooowah Booooowah.... really that is pretty much the extent of it....... cant even put it in gear...... So with a toe rope.... get it back to the house.... and somehow I miraculously massage gas pedal and it runs like this.... wubah wubah wubah..... into its parking spot...... No Joke.... on the expressions..... So I left it momentarily.... came back a little while later... and just checked out some things... The observation is this... Again.... idles fine.... once the throttle plate changes position.... the car is doomed.... like there is no more fuel being dumped into the car even though I am asking for it........ and if I put the accelarator to Wide open throttle...... It doesn't stall... it pretty much just runs like terd.... won't stall out..... I feel at WOT.... it is getting tons of AIR but, the same amount of fuel..... no more fuel than at idle..... Someone mentions check fuel pressure..... How would this be done? a special tool/gauge? If you could let me know.... seems like this is a good thing to establish at this point...... If there is anything else that may indicate other areas to check let me know.... Micky Link to comment Share on other sites More sharing options...
travmo86 Posted December 16, 2013 Share Posted December 16, 2013 Definitely check any codes for the CEL. 96 should have OBD2 so any auto parts store will usually scan it for free. My 93 2.2 is doing very similar to what you describe. Unfortunately being a 93 I have the good old blinking light. Not very helpful in my case. All its throwing is an O2 sensor code. However I believe that the code is probably more the face that its running rich as all hell more than a malfunction in the sensor. I have a heavy exhaust smell with mine.

travmo86 Posted December 16, 2013 Share Posted December 16, 2013 Sorry just saw the top where you have some misfire codes. What codes are they in particular? Link to comment Share on other sites More sharing options...
okamikai Posted December 17, 2013 Share Posted December 17, 2013 (edited) You can do the fuel pressure test yourself or you can take it to a dealer or shop, its around $45 for a fuel pressure tester, and about $60 - $70 for the dealer or mechanic to do it.

okamikai Posted December 17, 2013 Share Posted December 17, 2013 The Throttle Position Sensor could be bad, it sends a signal to the ECU that the throttle is open/closed so it can send the proper amount of fuel to the injectors. Its inexpensive to replace; around $50. You should try that before anything else... Link to comment Share on other sites More sharing options...
mickytrus Posted December 17, 2013 Author Share Posted December 17, 2013 Is there a way to test the throttle body positioning sensor..???? Yeah, could be that... make sense.... like can I check it for resistance... or continuity...... through the connectors what usually craps out on them... Here are the codes: p0106 p0301 p0302 p0303 p0304 Link to comment Share on other sites More sharing options...
mickytrus Posted December 17, 2013 Author Share Posted December 17, 2013 P0106 Pressure Sensor Circuit Range Problem P0301 Cylinder 1 Misfire Detected P0302 Cylinder 2 Misfire Detected P0303 Cylinder 3 Misfire Detected P0304 Cylinder 4 Misfire Detected Looks like from the codes more like an ignition problem rather than a fuel problem.... Pressure sensor circuit range problem? Any thoughts?????? Perhaps, like above..... someone said.. check timing belt...... I should probably do that..... Open for suggestions.... Thanks....

Crazyeights Posted December 18, 2013 Share Posted December 18, 2013 (edited) Try another pressure sensor. I just fixed the same problem on a '96 last week. Edited December 18, 2013 by Crazyeights Link to comment Share on other sites More sharing options...
mickytrus Posted December 18, 2013 Author Share Posted December 18, 2013 Ok, I will try another pressure sensor... What is a pressure sensor "sensing" and where might I find it..... Thanks,..... and a pressure sensor... could affect and create misfire codes???? I don't know ??? I am just asking...... I always like a sure thing... that is why I ask.... thanks, Micky....

Fairtax4me Posted December 19, 2013 Share Posted December 19, 2013 P0106 is for the MAP sensor, which measures manifold vacuum and barometric pressure. Most of the time you get that code because of a loose or split vacuum hose. I had a P0106 code for 3 years and it never affected engine operation. The MAP sensor is a low priority sensor. The ECU only makes "fine tuning" adjustments based on MAP sensor inputs. And once it sets that code the ECU disregards MAP sensor readings anyway. Check the vacuum hose to the sensor, make sure its attached. It's the small black cube on the passenger strut tower. It has a short hose to a solenoid right next to it, then a long hose that leads to the intake manifold. Double check all of the other vacuum hoses, and check all of the breather and PCV hoses that attach to the intake tube. Make sure they're firmly attached and have no splits or cracks. 1 Link to comment Share on other sites More sharing options...
mickytrus Posted December 20, 2013 Author Share Posted December 20, 2013 Thanks, I'll start with map and the hoses.... and then probably should just check the timing belt too..... then check fuel pressure... Ill post with results.... Link to comment Share on other sites More sharing options...
upnorthguy Posted September 5, 2014 Share Posted September 5, 2014 My wagon popped a P0106 code this morning. Found this thread and did some searching...when I was cleaning the IACV I must have knocked one of the vacuum lines off. Found it and reattached. Thanks!
