Let me start by noting everything I've done, because I know you will tell me to do these things first:
- Compression tested, I have great compression (up to 182 psi)
- PCV valve replaced
- TPS replaced
- Checked for vacuum leaks
- Checked tension in the throttle cable
So here's my issue:
- Idle surge (down to 700, back up to 1000)
- While driving, when I push the clutch in, the rpms go to 2000, fall down to 1200, then rise back up to a steady 1700. Putting the car in nuetral makes no difference. When the car is in motion it will idle there forever. But as soon as the car comes to a complete stop the rpms go back down to idle (still surging of course).
- And I am still experiencing blow by symptoms
I'm thinking the IAC? What do you think?
