i doubt its the ECU.

when were the O2 sensorSSSSSSS (there are 2 and need to be replaced in pairs) replaced?

the dealer told me my ECU needed to be replaced as well, that was 2 years ago. (i suspect the dinan chip confused the reader or something???)

i would start by replacing the O2 heater relay, and the DME relay, and cleaning out the ICV.

however, do a search relating to the charcoal canister, i replaced mine recently and startup idle is significantly improved.

im replacing my engine mounts next week, and hopefully that should fix all my engine issues for the time being, untill i redo the intake manifold gaskets, which are causing my engine to shake do to unbalanced airflow at idle. (or maybe its the fuel injectors, who the hell knows!?!?)
