Nah, this is the one I swapped the engine in.

A few things that I know about so far:
  1. Right side ball joint to finish passing inspection - nearly $60 and 5 day wait time... dealer part
  2. Code P1640 (quad driver output module 1) Basically, this means that either the ECT or Cruise module aren't working correctly. The other two things on this circuit are dummy lights that both work during POST.
  3. Transmission isn't shifting correctly, waits till like 4kRPM to shift out of first even at very low throttle... assume this is related to the P1640 issue, so it's probably the cruise control module. Quick fix is to disconnect the CC's throttle actuator cable from the throttle cam, so it can't affect throttle anymore.

I might have to remove and clean/rebuild the throttle body, as well, I don't think the IAC solenoid is seating correctly in the bore, which explains erratic idle while coasting.

I'd like to think that people might open their eyes at some point... instead, I find it more and more likely that I'll just close mine.
