Car will stall while idling after sitting overnight or whenever the engine is cold. Does not stall after driving a few miles, but it ALMOST stalls and comes back to life as RPM's drop.
Previous owner says he replaced all fuel lines, intake boot, and vacuum hoses. I think the car has a vacuum leak, and I'm going to try to pinpoint where this weekend with some carb cleaner.
Maybe it's leaking from the brake booster?
When revving the engine in neutral, the RPM's dip first and the engine hesitates for an instant before things start working as they should.
Do these problems sound related? It was running very rich previously based on scent, but I replaced the coolant temperature sensor and it doesn't seem to be running as rich anymore.
The exhaust is also very loud and it sounds like it may have a hole somewhere.
