Been working on a 99 SE with the 3400 with 98,000 miles.
Cold start is fine, but when you drive it some...stop...wait a couple minutes like going into a store or something and come out... start-stall...start-stall. Then finally it will start.
Here is what I've done so far:
First, the car came to me with ALOT of problems. It amazes me how people don't take car of thier cars.
1. I replaced the leaking intake gasket.
2. I replaced the leaking water pump.
He brought the car back with the start/stall problem.
3. His fuel gauge was reading all crazy so we replaced the fuel pump unit with a good used one (wrecked GA with 4k miles) Plus I wanted another pump to make sure that wasn't the problem.
4. I cleaned the throttle body and IAC motor. I also hooked up a scanner to make sure there weren't any codes and to "work" the IAC motor. I would raise and lower idle no problem.
5. Check fuel pressure. Holds good, don't leak off.
6. Replaced original plugs.
7. Looked for vacuum leaks, AFM hoses tight, etc. Nothing found.
Everything seems to be good, but the hot start-stall continues... I'm at my wits end. Any ideas?
