Bimmerheads,
I need your help to find the gremlin in my 1988 325is. The engine intermittently cuts out. Recently the check engine light would flicker, engine stumble slightly, but did not stall. The last time it stalled, it was under load at highway speed. Didn't notice check engine light since I was more focused on getting the car to the shoulder. Car started up afterwards. I have replaced the following and still experience the same:
- Fuel filter
- CPS
- Relays: Fuel pump and engine management
- Fuel purge valve
- TPS
- O2 Sensor
- Cap and rotor
Fuel pump was replaced 50K miles ago.
I am inclined to replace the ignition switch and plug wires. Only other item is the fuel pump.
I appreciate any insight.
Thanks.
