Re: 91 PAU Starting Issue

Definately scan for DTC's and post any hard/soft codes. that would be helpful.

Also check what the reported engine temp is and the ECm is showing a constant toggle from rich to lean or is it purely stuck to one side the mix.

2 possibilities off the bat are ICM or crankshaft position sensor[circuit].
