So its been a hot second since I have been here, but I have a problem that I can not seem to fix. I have a ATQ 2.8 that about two weeks ago I got a sweet misfire. I ran my vagcom and got p0300 p0301 and some other randoms like bank 2 o2 short to ground. and the lovely abs light/code.
I have replaced all the spark plugs which now has made things so much better, but under full load and not all the time is misfires and then will "pull" it self out and run like normal. < Which means I WOT it runs normal it hits about 5k misfires till about 6100 then is normal again. And the misfire sound like a launch control system. I also replaced all the broken vacuum lines that I could find. Would should I do next?

 

What part of Charlotte are you in?

 

kinda south charlotte

I live off of Rama road and I work off of Monroe road by Sardis road

 

Is it misfiring on all or 1 cylinder?
a guy I know had almost the same issue- swapped coils around and the misfire moved.

 

^^This^^ Though 0300 is usuall more than one cyl. Have you cleaned the MAF?

 

So can I clean the maf with brake parts cleaner. And I just need to find someone with a set of good coils

 

That's what I do. Unless you have a tamper-proof torx, you might have to take the screws out with a pair of pliars. Then take the screws to a good hardware store and get some allen heads.

No. If the code is just for one cylinder, swap coils with another cyl. If the code moves, you've got your problem. If not, might swap fuel injectors with another cyl and see if the code moves.

 

How would I swap around coils if they are all one piece.

 

That's right, no coil packs on that motor. I'll PM you a pdf on how to test them.

 

ahhh thanks man will do it after work
