My 1989 Chevy Celebrity 2.8 V6 will not idle, it starts fine, but won't stay running without pressing the gas pedal.
I have replaced the E.G.R, T.P.S, M.A.P.S,
and the throttle body. The fuel pump was
recently changed and has been checked.
Tune up was done 5k miles ago. Please
Check for a vacuum leak, they make a smoke kit to help find the leak...
Checked for vacuum leak, none found however, the car now starts fine and idles but there is a slight surge, after it warms up, the surging is more prominent, after about 10 minutes, it shuts off and won't restart until it cools off for a couple of hours.
