Stuttering, (electrical or Fuel problem)

Question for the 4 Ring Gurus out there, I have a 1999 A4 2.8L Quattro and am getting a misfire code dectected, cylinder 4.

Now so far what I've done, to diagnose this problem is to

Change Fuel Filter,

Change spark plugs in all 6,

And yesterday Change the coil packs.

The last thing that I've got to do is to test the spark plug wires, and how to do it other than change the location of two wires...

I was curious if there are any other ideas floating around out there.

Thanks in advance.

Should have searched more throughly before hand, but I found this and wondered if it could be valve cover gaskets.

Quote:

I also replaced the valve cover gaskets, and like you said, wasn't difficult at all.

Now that I've been under the hood so much the past few weeks, I understand the coil pack/ignition control module difference.

I just had the CEL code pulled at it was a misfire in cylinder 3. Turns out it was the spark plug wires. Replaced them yesterday and it's good as new. The wires are expensive for our cars (~$160 for the OEM Bosch). Hopefully the wires fix the issue for you too. Let us know how it goes for you.

Note to the OP: You would have been better off posting the question in the forum for the Audi model you pushin, as opposed to the Gen Tech section. Especially in and around the holidays. Double-especially since you're askin about an A4. The various A4 sections are easily the most viewed, and best attended sections here.
