I have a '99 s10 with a 5.3 swap. It's running off a 2002 silverado tune file and a 411 PCM. And a cable throttle.
I've figured everything out and it runs great but I added a/c. Didn't really change anything tuning wise, but now it cruises with the a/c on only.
Like going through a shopping center it doesn't need my foot on the throttle at all. I can shut the a/c off and it drives normal.
Everything is wired 100% like the factory had it.
Can anyone guide me to fixing this problem?
Thanks.
