if its not one thing, it seems to be another. just got her running, and now she starts getting cranky already. Started with unplugging the same uvch that I found to be the problem last time. then, I unplugged the icp, plugged it back in, and no change. Last time I did that, it killed the motor. Stopped engine, I unplugged the icp, started it, drove it, she drove fine, with no miss, and full power, accompanied by the "check your wallet" light. Someone has had to run into this one before, Bad icp?

 

Sounds like it... The CEL light is normal when unplugging the ICP sensor...

Is there any oil on the ICP sensor?

I'm not sure I understand what you were saying about the UVCH plug though..

 

last time I was fixing her, I unplugged the harness connectors at the valve covers one at a time to do a manual contribution test, and isolated it to the injector feedback signal wire in one plug.

The icp sensor has some silicone on the top of it like it started leaking on someone else before we bought it in april of 2010.
