Whats up everyone. Hoping someone can point me in the right direction with this issue.
Its a 02 Envoy with the I6 and about 144k.
With the truck in park at idle, if you tap the gas pedal, the rpm's drop to about 300, the motor stumbles a little, then it revs up and falls back to idle.
Hasnt stalled, but seems really close to it.
Have another issue going on, not sure if they are related. Thinking the exhaust manifold is leaking. took the heatshield off to take a look, and didnt see any cracks or holes or soot, but it really sounds like an exhaust leak on the passenger side front of the motor.
Started as a ticking noise, so we took it to the dealer to diagnose, they said the water pump and fan clutch were making the noise, so i replaced them on my own. But still has a little tick and what sounds like an exhaust leak.
Just need a little direction. I can replace parts no problem, but suck at diagnosing what the issue is.
Thanks for any input.
Andy
