oscillating idling....what's that about?

[Phoenix_RsX]

After installing my intercooler and 780 cc injectors.....I of course decded to start her up. The problem is:

My car is now having an oscillating idling from 1400-2k, which is making my turbo beging to spool up.

Also, no matter how positive I set my SAFC to, it still runs VERY lean

Any ideas?

Yeah, I agree. Do a leak test. Pressurize the system with the car off. It's easy to do. I think you might find your culprit then.
