I'm hoping you all can help with a random stalling issue on a 1992 Series 1 3800 (L27). Yesterday the car stalled four times . It restarted each time.
The last time I was driving:
The last time I was driving:
- Cruising about 45 mph, straight, no bumps in the road.
- It just stopped running - no chugging, no surging, just died.
- I had a fuel pressure gauge hooked up. Pressure was fine before and after the stall (~45 psi).
- Had a vacuum gauge hooked up - looked fine until the stall
- 16 in Hg of vacuum at idle. All hoses look good. Sprayed carb cleaner all over - no changes in RPM.
- 1992 engine does not use EGR.
- Catalytic converter is not plugged
- Wiggled key & ignition switch, seems OK.
- Recent plugs, wires and upgrade to Type 2 coils/module (used from L67 motor)
- Connected a scan tool. TPS, O2, MAF all look OK.
