BMW 325e stalls

[liddaguy]

I have a 1986 325e, automatic with 120,000 miles that stalls only when warmed-up and for the most part at idle or accelerating at low rpm from a stop. Problem gets worse on a hot day or if the car is running warm-(stop and go up hill). I can usually restart with a lot of cranking and throttle. It has the same trouble starting if warm after recently turned off. It acts a bit like an older manually choked vehicle with the choke left on. However, my mechanic says that the plugs show a lean burn. It runs well at freeway speeds, though recently it cut in and out while accelerating onto the freeway. It ran well above about 50 mph. The previous owner said it behaved similarly at about 70,000 miles. She replaced a lot of expensive stuff and finally an inexpensive computer chip did the trick. Unfortunately she doesn't remember what it was. The records show that around then she replaced:
AF meter
Computer
O2 sensor.

Could the O2 sensor be it?

Dude...I'm not a mechanic, but this exact thing happened to me on my old 86 325es...I had just changed the spark plugs to bosch platinum and the trouble started...It would stall ALL the time, even going down the highway...I had it to 3 diffeent shops here in town and noone could figure it out...I finally took it to the bmw dealership and they charged me over 900 bucks to "fix" it...IT DIED LIKE 10 TIMES ON THE INTERSTATE COMING HOME FROM THE DEALERSHIP !!! I called my parts guy at Bavarian Autosport and he asked me "You didn't happen to put those bosch platinum plugs in it ?"
Mother f***** !!! The bosch platinum run too hot for the car ! I changed the plugs to some cheap ones and the car never stalled again !

You might also check your plug wires and the distributor...For some reason the distributor on mine needed to be cleaned of corrosion about twice a year....Good luck !
