Hi all, I’ve searched through the threads and found similar but not the same issues. Here is mine: While driving normally, either cruising on the highway or around town. my 89 325i vert will suddenly lose all electrical and engine power and coast for a few seconds after which it "switches" back on and everything is fine again. It has done this about half a dozen times in the last two months. I have replaced the following, Crank sensor, CO2 sensor, throttle position switch, rotor and cap but the issue still baffles me.
Any ideas what to check next? Thanks!
