1999 2.4 l chev cavalier 200 000km
Wife took a trip, car running just fine, stopped to shop, was hard to start, finally started - drove for about 15 min - went into campground, car wouldn't stay idling, eventually stalled - couldn't restart.
Can put to floor, will start, feathering throttle, but will stall (running very rich)
Brought to garage to diagnose - said it was ignition coil or module. Got a "tested" unit from wreckers (whole ignition assembly w/housing) Dropped it in - same problem - garage full of shit.
- Checked all vacuum (and Map sensor) all seem good
- NO Codes on computer (have an actron scanner)
- Fuel pump charging (I changed filter - no effect). No valve to check pressure.
- When I am able to start
- eventually stalls (too rich - fuel in muffler)
- can can get it too level out smoothly for a few seconds - coils ok...
- I dont think its fuel supply (unless regulator shot)
- I dont think its ignition coils/module
- Timing?
- Computer?
Simply not sure what to try next....
Any ideas greatly appreciated.
Thanks
