Hello and welcome!My name isCustomerand I can assist you with your question.
Is the check engine light on? Are there any codes?
Do you know what the engine vacuum is at when the engine is at idle?
Hello and thank you for that information.
When I was asking about vacuum reading, I would not talking about checking for vacuum leaks. I was talking about checking engine vacuum to see how well the engine is breathing. This is very important.
We need to watch the oxygen sensor reading under a load when the engine stalls or bogs down under a load. This will tell us if the engine is starving for fuel.. which I suspect it is.
Also, have you checked for plugged exhaust?
Ok, good! That takes care of the restricted exhaust theory.
