1994 Chevy S10 4X4 4.3 TBI engine.

Asked by Pops72 Aug 12, 2015 at 04:35 PM about the 1994 Chevrolet S-10 LS LB 4WD

Question type: Maintenance & Repair

A while back the engine would gradually slow down and die. Will not idle. I have replaced
the map sensor, taken egr valve off and cleaned, new temperature switch, different throttle
body, new fuel pump and filter, and new computer. It runs fine for a few minutes and the
start idling really rough and eventually dies. Checked all vacuum lines. Any ideas?
