I'm Awesome
Truck is a 94' Yukon, TBI. Recently rebuilt/resealed the TBI, and put in a new distributor and set timing.
At the beginning of this summer, I tried raising the idle a little bit for more AC performance, not realizing that the IAC would just bring the idle back down. Now Im trying to correctly reset the Idle screw.
I turned the key on with a paper clip inserted into the A and B terminal, but didnt start, waited for 30 seconds and unplugged the IAC. I then started the truck and attempted to reset the idle rpm to 650, problem is, the rpm immediately shot up to 1600. Backing the screw all the way out only bought it down to 1200rpm.
Do I remove the A and B jumper before starting? Maybe I have to unplug the timing advance?
Clearly Im missing something here. Figured Id come to the experts before I attempt it again.
