Car wont idle

[RaysTsi]

I recently did a 6 bolt swap with a 1g head, 2g intake mani, 2g tb, and now my car wont idle at all. I replaced the ISC motor with a good one and my car still does not idle at all. What else could be wrong?

Base idle set screw (BISS)?

It sometimes takes time for the ECU to get the idle right. But would definitely check the intake for leaks.. then check/adjust the base timing (s/b 5deg BTDC) and then the base ide (s/b 500RPM).

Good luck!

however the idle should be a little higher than 500rpm... shoot for roughly 750-900 (as long as it doesnt start searching) May I ask why you are still using the 2G intake equipment?

I bought I lot of high quality $$$ parts for my car......

The money train came to an end....

Okay I checked the intake psss, vacuum hose was comletely loose, I clamped it down. Checked the BISS it was all the way down, I screwed it out 3-4 turns. My car still doesn't idle, when I start it I have to give it a lil gas and if I give it a little gas and then let off the gas peddle the rpm will shoot upto 1500 and then settle back down at 0. WTF?

If you have a boost gauge, what does it read? Do an intake leak test. I just recently swapped another 6 bolt into my 96 in 14 hours with major problems. Maybe your intake manifold gasket is leaking. I set my idle for 900 rpms. Let me know how it goes.

at 1000 rpms it reads -10hg
at 2000 rpms it reads -19hg

If you haven't gotten your idle fixed as of yet, it looks like a vacuum leak to me. That is if your engine has the stock cams in it.
