Misfire cyl # 4, not the plug, not the coil. I'm not sure how to check the wire, or where it leads to HELP!!!
Oh, sorry, its an 01 a6 2.7t new nkg's, gapped at .028, blew out an sti coil pack last wk(2 wks old) now replaced with new BERU coil pack, still misfiring...I'm assuming the wire is bad unless there is anything else....I never saw wires like thi before

 

Are you using the Audi shop manual CD?

 

Huh? I 've been using the process of elimination, I wish I had a manual, CD or any

 

Cliff! Cliff! Cliff! Cliff! Cliff! Cliff!

 

Alright, seriously.....I need some help here before I go even more ****** insane, the service dept(Wyoming Valley ripoff artists of N.E. Pa,) cant even get me in until almost 12 days from now! I think this is something I can tackle myself if I talk to someone who has done it before...

 

Sorry I couldn't help myself. I have to admit I know NOTHING about 2.7's. I think the wire could be suspect but what about the engine computer? Would the vag-com detect a bad computer? Do the 2.7's have ignition control modules? If they do have icm's are there two like the 2.8? If there are can you switch them and see if the problem moves to a different cylinder?

Sorry I am of no help. Just thought I would throw out some thoughts to placate my guilt for chanting clif! clif! clif! clif!

where are the ICM's...I'm pretty mechanically inclined, but I'm new to what the **** goes on under the hood of these cars...Thanks for any input, even the cliff comment because at least I was able to laugh for the first time since I started ripping my hair out a fewe days ago

 

After looking in the Bentley manual I don't think the 2.7 has icm's after all.

When did the misfires all begin?

one more thing, are you sure it is getting adequate gas? You could switch injectors.

 

The misfire started about 2 weeks ago. I put in all new spark plugs, all oem, all gapped at .028.---no change. Scanned at auto zone, got a misfire on cylinder 4. So I switched the coilpack back to cyl 5 and it followed. Bought a new coil pack, STI brand, 12 days later, misfire on cylinder 4 again. Heard bad things about sti packs, heard that they blow out on turbo motors, so today I got a brand new BERU, still misfiring

 

before I put the BERU in today, I pulled out the old sti and started it, to see what would happen, and I got no change in the way it ran , even w/o the coil in it. Then I pulled the plug out and it was wet with fuel
It did run perfect though for the first 12 days Iafter I replaced the first coil pack...Thats what lead me to believe maybe the problem was the wires, and the coil pack was just a temp quick fix?
