Hey guys-

I'm having some serious idling problems... The car surges something fierce and used to smell rich (Ed Wright reprogrammed it for the correct MAF). I got the computer back and the surging problem remains.

Here's the specs on the car:

- Ported aluminum heads
Flowed 263I/205E
1.6 Rockers

- Custom Cam:
Dur. @ .050 - 214I/224E
Lift @ Valve - .504I/.524E
Lobe Sep - 114*

- Ed Wright programming (a friend plugged his basically stock PCM in and it idled much better)

So far, I've checked the EGR (still running it), IAC and TPS (when I unplug the TPS the car idles fine). I'm just looking for any advice on what I can check next. It's really frustrating me now.

Any help is greatly appreciated! Thanks in advance!
