I have a 94 yukon that I bought off a guy locally. It has a few issues that need to be solved but the main one I wanted to get some input on is it tends to idle funky, not all of the time but when youre sitting in drive at a stoplight, it starts loping like its going to die. Almost like it has a cam in it. Then when you are slightly on the gas you can feel it loping again. Should I try replacing the Idle control switch? Im going to try to pull the air filter box off and see if the intake is clogged first. It also has an k&n fipk intake that goes straight into the manifold so there might be some funk there. Its gotta be that or a vacume leak somewhere. idk




truck is lifted 6" on 36's rear had a 2" block sitting on a 4" block when i got it so im sure there is a lot more hack job repairs to come in the near future



thanks for your input

is the fi system 94 or 97?

97.

Wait, who did the motor swap? The PO?

ya I had nothing to do with it. I need to off this thing. the deeper I get into it the sketchier it gets. The torsion bars are maxed out, the ball joints are smoked, the rear suspension is tweeked, the driveshaft hits the body if you floor it. who knows what else Im going to find. I'll make a bad ass truck if someone wanted to drop a grand into it
