alright alright back in the states finally and army free for now.

back in germany i went to take out my spark plugs i had posted the pics on the website a few months ago of the plug spining out and leaving the threads on of the plugs in the cylinder i extracted it out and it came out fine no problems.

ordered some autolites from rockauto thought they were gapped at .35 come to find out they were gapped at .45

got a free set of acdelcos from rockauto and ordered a back up set. installed them and still had a misfire and flutter effect when getting on the throttle. in germany i had tried gapping down to .30 and still had the same problems.

so anyways car finally got in from germany bought a cheap code reader from advanced auto and i poped 6 six codes.

P0300
P0302
P0304

p0302
p0301

thats the order they came off the code reader. Now my question is are my coils bad? new plugs bad even though they look good? Or the controller gone bad?

thanks guy!

 

Mods?

 

Missfire codes on all cylinders but # 3. Try reseting the ECM if everything is in ok. Also same gas In car since you been gone ?

 

i got the old hahn bsr tune since ive had the car, hahn cold air intake, hahn exhaust thats all so far need updates but other than that. it ran crappy in germany when i did that stuff and still runs like crap right now. threw some new gas in it last night.

how do i rest ecm uplug it?

cause in germany i cleared codes with a code reader there and disconnected the battery there too and still when i would try and get on it id flutter out. so i think its more than just a rest but i could be wrong

 

Welcome back home, Austin has a close crew im sure they could help ya with anything ya need if ya ask em. U gotta find em tho lol i forgot the website Gmtexastuners.com or somthing

 

You could move that #3 coil around and see if the code changes with it, but it seems highly unlikely that you got 3 bad coils all at once. It's happening under load, which suggests coils, but I think you should switch everything back to stock and see if your issue goes away. You can narrow it down from there by replacing the parts/tune one at a time.

 

get new plugs but before u do replace them check compression. ....... if good replace the plugs and get a real tune.

 

Do what tech do... clear the code, drive it and see if you can reproduce the error

 

What this dude said. It's definitely time to check compression and for boost leaks.

Notice anything funky at idle?
