got a problem with my e34 525i.Car drives fine,except for one creeping problem with the idle.car will die off each time I stop it at lights etc when in N position.doesnt matter if the a/c is running or not,the idle will drop to about 500rpm and then just flame out.starting it again is not a problem eachtime.
Have replaced the idle valve,done a full diagnostic(no fault shown),checked all hoses for leaks.My mechanic suspects it could be the ecu.
anyone can help?

Hi could be a silly question but have you tried turning the idle up a bit on the throttle

done the tuning to as much possible,but still no help.cleaned the maf as well.

I've never heard of an ECU doing things like that, but it sounds like you have a good excuse for a performance chip.

Does the car run fine otherwise?

Possible TPS?

yeah, the car runs excellent.its just this idle thing i havent been able to fix since getting the car 3 months ago.
perfomance chip..gonna cost be big bucks here in malaysia,but sure would like to sometime

I can't imagine shipping of a small electronic chip would be that bad.

I had a sorta similar problem with my 535i (http://forums.bimmerforums.com/forum/showthread.php?t=588392). Different car but something to consider.

JMI
