And what are some good ways to clean it out? Chevy wants $600 for the part, and I do not even know for sure if it is the actual source of the problem. Truck just got whole new ignition system, from distributor, wires, plugs, cap and rotor, coil, the works, and now it runs worse than it did before the work. Rough idle, slow to accelerate, high rev when in park, hard gear shift, almost sounds like it is getting ready to stall. I am getting ready to drive it off of a cliff soon. Anyone else having this problem??
Excellent website, but doesn't have the repair book for either the Chev or GMC make........my luck of course.
I don't know if it makes a difference, but it is a 7.4 l V8 K2500 3/4 ton 454................
YEAH I had same problem, Hold it try the 02 sensor I had the same darn thing happen to me,I replaced the wires, plugs, cap and rotor, coil &pickup coil and controll module and it still ran like cr*p when i put that new 02 sensor in ran like new for a 300K mile truck.
