Not holding idle

Was your pim still highlighted? If so you have a faulty pim sensor. You may have damaged it during the engine bay cleaning or got it too wet or that sparking on the airpump fucked it. Crank angel sensor is behind the crank pully. I dont think its that.

I think your pim is out some how & you need to get it hooked up to a Datalogit to see if its still on value 1 and not any of ther others. Also if its seen to high a volt from that spark that will do it to.

Do you have a stock map sensor? That may also be poked. 2 things to try...get hold of a nother pim & map sensor. Plug them in 1 at a time to see what happens. If the problem goes away it was the sensor.

If this dose not work then Unplug your TPS and see if it idels. We had a car once that had a TPS that just jumped around all over the place randomly with the vault reading & the car would not idle properly. It never highlighted on the PFC either. So we unpluged it and it just smoothed out right away.
