Here's the scoop. I have a 98 6 speed car cam + bolt ons and having problems getting the car to idle when the A/C kicks in.
Mods:
G5x3
TPIS headers
usual bolt ons

When you start the car up it idles fine but when you turn on the A/C, the RPM's drop down very low and either cuts off or bounces around for a second and idles rough. Any ideas?

Have you already tuned your idle airflow tables? Does your ac airflow adder pid match the actual airflow increase when you turn your ac on?

We have a good tune on mine with a G5X2 cam and with the A/C on mine idles up to 2000 to 3000 rpms. Sounds like we have opposite problems.

should just have to adjust the idle air for the ac, but i assume you have done this already?

Dont move it too much because if you do and you go past the sweet spot you will see the same results. move .1 at a time

I also have the same problem as juiced_z28 cuz my idle hangs when coming to a stop w/ the ac on. Without AC everything is perfect. So its the idle air or the ac torque table that needs adjustment?

when the ac comes on you should beable to tune the raf table to fix it, just look at the idle air trims and adjust like you would regualr idle, i am assuming this though because i have no ac so i havent done it
