Check engine light came on. Car shifts fine, runs smooth at idle and at normal driving. I checked the usual "forget me" suspects (fuel tank cap, Winter/Sport tranny switch being in between, etc.).


The only thing I noticed was a funny behaviour at idle in Park....I warmed up the engine, and ran high RPM - 4000, the engine misfires/shakes badly. This doesn't seem normal....anyone see this before.

Car is a '99 e430, 83,000 miles.
