Coil pack problem or something else?
MY 2001 1.8TQ has started having a very rough idle. Runs fine and has plenty of power at higher RPM.
Vag-com reports the following codes:
16684 - Random/Multiple Cylinder Misfire Detected
P0300 - 35-10 - - - Intermittent
16685 - Cylinder 1 Misfire Detected
P0301 - 35-10 - - - Intermittent
17584 - Bank1: O2S (Lambda) Correction Behind Catalyst: Control Limit Reached
P1176 - 35-00 - -
16686 - Cylinder 2 Misfire Detected
P0302 - 35-10 - - - Intermittent
16688 - Cylinder 4 Misfire Detected
P0304 - 35-10 - - - Intermittent
Cleared codes, ran engine for 2 minutes and got the same codes:
16684 - Random/Multiple Cylinder Misfire Detected
P0300 - 35-00 - -
16685 - Cylinder 1 Misfire Detected
P0301 - 35-00 - -
16688 - Cylinder 4 Misfire Detected
P0304 - 35-00 - -
16686 - Cylinder 2 Misfire Detected
P0302 - 35-00 - -
Based on my searching, it sounds like it could be a coil pack problem, but what are the chances that I would get 3 bad coil packs at once????
I will try moving #3 (which seems to be the only good cylinder) around and see if the codes follow coil packs 1, 2, 4.
Should I look at something else, or go ahead and replace all four coil packs?
I know that the coil packs were replaced via recall way back in 2003, but I seem to remember that there was a second recall two years ago that I ignored? Does anyone know if there was a second coil pack recall, or is it just wishful thinking?
