Hi, What do I ask for when I get a Neon's coil pack... What years? Thanks, Artie

Thanks Daddycoolj, I traded that sensor, it's for the ECM, not the gage, and the same problem sufaced. I just know it will be something simple, if only I knew what it is. I just feels like a weak spark plug. Looking for more good ideas, thanks and keep throwing out ideas, Artie

13.2 idle and 13.8 at the highest.... I'm going to try some different spark plugs and I will check my compression, the misfire comes on very slowly and disappears rather quickly, faster than I can oull over, pop the hood, get out, open the hood, it already smoothed out. It will be a few days before I'm back into it, THANKS, 94 Loyale

Hi, I have a 1990 Legacy L 5sp. I have a miss that is driving me nuts... It comes and goes smoothly, meaning gradually starts to miss then as smoothly as it starts, it goes away. Usually happens when you accelerate slowly or hit a small grade. I noticed it when I repaired the AC, but it can happen anytime, cold warm or at operating temp. usually warm. It may go 50 miles and nothing, then start it up within a few miles does it. I have shaked and tugged, and pulled connectors and the wiring. It smoothes out around 3200 or so rpm on a downshift. I have removed the thermostat with no change. I have replaced the knock sensor and used premium fuel no change. I can turn the engine off and coast and restart the engine no change. I have put new grounds on top of factory with the coil pack, ACV, no change. I put in new NGK plugs gapped @ .043 in. I have replaced the following coil pack, igniter module, plug wires, O2 sensor, All 4 injectors, fuel filter, MASS, gas cap, PVC valve, knock sensor, fuel pressure regulator ECM temp control sender, THE ECM. the same results. I have looked and felt, sprayed to look for a vacuum leak, no change. This has been going on for 3 months, and many tanks of fuel. When it's having this fit, it really uses the gasoline. I did notice when it was doing this, the fuel Gage would slowly go towards empty, and than drift back up, I out an extra ground on the electric fuel pump wire at the sender unit. I may have forgotten what else I did to this, and I'll be grateful to the winner of "Guess the Gremlin sweepstakes" Throw out what ya got! Thanks, Artie I have 2 codes stored in my ECM that I cannot erase, 22 knock sensor & 24 ACV valve. I have pinnout the knock sensor wire and that rang out. There is no CEL light on. I still have the miss, Or I should call it a MISS-Fire. I pulled a plug wire of the good running Subaru and grounded a spark plug, the miss I have been describing is actuall a misfire. I am only partialy missing on the problem Subaru. The fuel pressure is smooth between 30 and 40, and reflects the change in vacuum. I hope somebody is still hanging in there with me. I have a very hard time thinking that the new spark plugs would miss in the very same manner as the ones I changed? I'm pulling my hair out on this rascal!!!! Any help me and my scalp would appreciate it! Any Subaru hotshots in NW Indiana?

Not so good update.... NO CEL, still has miss... 2 codes stored 22 and 24, I will let it sit overnight to see if they clear. Still misses.... New knock sensor installed. Let me know what yu'a think.... Thanks for viewing and inputing, Artie

Still have a CEL on. Codes 22 23 Knock sensor. I know where the Haynes says it is, but I don't see it.

EDT EDIT EDIT codeds 21 22 knock sensor..... Looking for it, now Thanks for staying with me Legacy777! I have a Haynes and I have gotten some wrong info on several things, one being how to read codes. After I read the sticky, I found out the right way. I had a code 14 and 16 1 & 3 inj. I read that a IAC would "confuse" the ECM and put a code 14. I cleaned it, now I got 21- coolant temp, 22-knock sensor, 23-air flow sensor, 24-IAC....I have pulled the battery, left it off last night. I will recheck my work and see what codes are stored. IAC wasn't too dirty, It did move easier, after cleaning. I do not have a rotary one, instead it uses a up and down duty cycle. I'll report back with my findings. The miss is very erratic, I have wiggled, tugged, jerked, inspected and cleaned every connection under the hood and ECM. ( all were clean) Gonna replace the fuel regulator, too. The miss I"m figuring may be a partial cylinder and can get worse (either a cyl. drops out all the way or looses another cylinder, which would be, pretty violent on 2 cyl?) I'll take the rope off my neck, get off the wobbly chair and see what I got. Thanks, Artie

Hi, I have been battling something simular to this. I will clean out or replace my IAC, and report back...

Thanks, Legacy tri-7, Not just with the AC on, it will miss without AC, takes longer. It happens on 90 F. or higher days it seems. I removed the thermostat and eventually did it again. If I drive above 3200 rpm, no miss, I downshift to 4th and smooths out. If I let it idle it smooths out. I gapped the new NGK plugs at .039. Old plugs read good. I ran dedicated, good ground to the coils. I have run 93 octane to rule out knock sensor. I have replaced spark plugs, plug wires, coils, O2, 4 fuel injectors, Fuel filter, MASS, ECM, gas cap, ECM temp sensor. The operating voltage is 13.8vdc. I have inspected the intake for cracks and bolt tension. HELP!!! If it was a horse it would have 20 or so bullets in it! Thanks for reading and / or replying, Artie

Hi, I still don't know what is causing my miss. I have looked many times for a vacuum leak, which would explain this condition. I would like to know if someone had found an unusual leak, brake booster, something like that? I have done the carb cleaner check for leaks, but I don't know if the IAC would cover this? Please keep me in mind and let me know, Thanks, Artie

no high idle just drops a (one) cylinder for a while, then runs ok?????? still working on it, with some more of your suggestions, Thanks, Artie

only one o2 and it has been changed. I'll keep trying,,,, Thanks, Artie

I will put another unknown compressor on and see if my hi side comes up... The system does balance after about 20 min. or so. tells me not plugged. Easy way or the hard way, here I go, thanks, Artie Update, I replaced compressor, evaperator, rec/dryer, revacced, and all is good, thanks to those who helped, Artie

Thanks all, I did use new NGK @.40, old plugs looked good, gap, deposits, color. I traded out with a good running same year, trans Subaru... OX2, 4 Inj., wires, coil, maf, fuel filter, not it. I have tried to eliminate everything that could effect 1 cyl from missing. It does NOT bog, stumble, cut-out. It will miss then before I'm able to stop and check, it smooths out. It seems when it goes into its fit use more fuel? I would think if it was the cold start going rich, I would lose more than 1 cly. and would set a cel? All the wiring appears ok ( in stock looms, etc) and every connector I touched I inspected and cleaned, and greased? I'm ready to cry and use profanity.... Thanks, Artie

Yep, the gage manifold was closed and ambient was 87 f or so. The hi side should be closer to 600-650 lbs or so? AC comp. on, teh comp seems like it doesn't load the engine, and I don't get the high speed fan action that should happen when the pressure switch goes closed. I'll probally get it fixed in time for our first snowfall!!! I have another Calsonic that I believe to be good.... I'll keep trying, thanks Scoobywagon and Legacy777
