I can't figure this out, when it gets hot out my car will randomly stall. I have to wait a few minutes for it to start up again. But it only runs for a few minutes after that. When it is cooler outside it has no problems. Now it also has a buggy, chugging feeling at lower RPM's, this has been goin on for a while and i think they are related. So far i've changed, the o2 sensor, spark plugs, coil, air filter, and have tested both fuel pumps and the pressure regulator. I'm all out of idea's, if anyone else has the a possible solution, please let me know. thanks

I would put my money on air flow meter, or idle control valve....the afm should throw a check engine light though.

haha, no check engine light in an 86 325e, a little before OBD1 was introduced.

depends if he has a motronic, or a jet-tronic ecu. because even motronic prior to OBD1 would throw a check engine light. would it not?

As far as I know, none of the 86 325e's did not have check engine lights. I know they have a circular diagnostic port, but it doesn't throw off any check engine light as far as I am aware. It doesn't on mine and non of the ones I have seen either throw a light on.

i have a similar problem. my 325e starts but dies shortly afterwards. somebody suggested i try replacing the DME located inside & above the glovebox. i have no idle problems so im not considering the ICV at this point.

i was told not to install it before 'checking it out.' by 'checking it out' does my friend mean to make sure it wont fry my exisiting circuitry? im pretty sure it wont b/c the replacement one i have has the same bosch part number.
