Engine/Transmission (1994 - 1998) A/C Killing My Truck

[JimDavis]

My 98 will either idel real ruff or die when coming to stoplights, giving a quik punch to the throttle and letting off, or turning the wheels while sitting still while the A/C is on. Any ideas would be appreciated.

Sounds to me like you need to idle her up a bit, you cam do this with the throttle linkage. I like mine idling at 900 rpm with the ac off.

The idle adjustment is at the back of the pump and you need a 10 mm wrench. Its difficult the first time as you can't see it without a mirrow. Losen the locknut, then adjust the bolt. Pulling the throttle helps to move the bolt in a better location. Do a search and I think there is a photo someplace of it.
