Hey all,
Been having problems with my 1998 A4 1.8tQ...i bought it used with Piper 270 degree cams, GIAC chip, and borla catback. It has a CEL due to misfiring. I have been told by a few people who also have the Cams that they should not be causing a misfire.
108,000 miles on the chassis.... ~5000 on the rebuilt engine
My VAGCOM scans bring back:
