As soon as I start the car the idle surges up and down and acts like it wants to stall, then does. I have just about checked everything on the "surge/idle" sticky here.

I pulled a newly installed plug and it was extremely wet with fuel. The exhaust smells extremely rich too. Would that cause the surging idle and stalling?

My fuel pressure is at 30lbs. w/vacum line plugged in and 38lbs. unpluged (Kirben regulator)


Thanks for any input.

Check out the surging idle sticky at the top of the forum list.

My car does the same. I believe the FTI cam is the culprit. The factory programming in the PCM doesn't get along with the current engine combo. Once the computer goes into closed loop , my car runs great. It looks like the only fix is a PMS or Tweecer.

I just noticed that you have checked the surgin idle sticky. Sorry.

It is wet in every cylinder or just one? You may have a stuck injector.

My car behaves much the same way when cold. I'm working on tracking it's issue down also. When it's warm it's hit or miss if it'll idle right.
