500E only behaves bad when cold!
 

My wife had to take the kid to school in my car yesterday morning and she has had it with the car and possible me!

I'm use to the ASR (limp mode) in the morning. I drive until warm and RESTART the car once or twice and it's almost fine after a stall or two.

The rest of the day the car is fine.

I need to FIX it to save a marriage! Is it the EZL/ICU, the TBA, wire harness or O2 sensor? I've changed Cam Post Sensor, cleaned the TBA, changed the plugs, rotors and fuel pressure regulator.

1993 500E 73,000 miles.

There as too many things that can do that- time to spend money on a real tech if you ask me. -no offense-

If you insist on being a DIY guy, check the basics like thermostat, ECT sensor, stuff like that before you repl. loads of parts. Good luck.
