I have yet to find a solution.
I do, however, have a question.
Won't significant engine misfiring result in a CEL?
To me, this eliminates the ignition system as the source of the problem.
Early flooding problems with the car seven years ago and subsequent misfires would always trigger a CEL. The light would clear by itself after a day or two.
Comments?
I would get a CEL if I held it for a long time (hight load low RPM and missing). After I drove it (normal) for a while it would go away. If I drove it (normal) I would not get a CEL even if it was missing for a short time in each gear.
