Default HELP ME! Engine is hesitating - Cylinder 2

CAR: 1999.5 A4 1.8T Quattro

I was driving my car and it started hesitating (missed firing on one cylinder). Checked it out and it was cylinder 2. The coil is fine, the spark plug was fine, the compression is fine (150). I changed to NGK spark plugs, I had the injectors flushed. But still cylinder 2 is misfiring.

Any ideas?

Do a search on power output stage, or ignition amplifier.

Default The ignition amps on the nDBW cars seem to have an issue with cylinder 2.

The issue seems to develop around 3-4 years of age. A couple people have dissected the ig amps and confirmed the issue.

When you say SEARCH - you mean what exactly? :-)
