I just changed the plugs on my audi bcz the engine light came on and the code was miss fire on cyl #7 so they said it just needed a tune up well now the light just came back on and its a miss fire on all 6 cyl,???????????????????????????????????WHAT DID I DO WRONG?

 

did you put all the plug wires back in the same way they came out ? is the plug gap correct for your audi? all i have hope it helps

 

how the hell do you have a cylinder 7 on a v6? a misfire doesn't only mean a bad plug. it could be your coil pack.

 

sorry i meant cyl4 i hit 7 on acident

 

well if it was a bad coilhow did it get from one being bad to all 6 in a couple of days

 

could be your ICM or ECT. change the ECT and test the ICM. usually the v6 engines don't misfire though. what plugs did you get?

 

used the cheapest ngks

 

describe in detail how you took the old ones out and put the new ones in

 

1st i took the passenger side ones off, i removed the air intake then the wire harness to the 3 coils then went front to back then did the same to the other side.

 

did you tighten the plugs on right? your coilpacks have a screw holding it down right? are they all on snugly? change your ECT too. i'm not sure how much it is for the b6 but the b5 it's only 7 bux.
