Ok well I previously posted a thread on my idle problem and here is the update I took the ICV off and cleaned it with brake cleaner and the car idled great for about three days i just got back from a 15 min joy ride and i was driving a little bit faster then normal hence the "joy ride" but as soon as I came to the stop light and stopped the idle went all crazy any helpfull ideas would be much appreciated thank you for you help

I am not gonna ask the question i want to as certain quarters will only moan. Some else care to do it for me?

Have you got any performance issues/decreased MPG?

Could also be a vacuum leak somewhere, have you checked your intake boot for damage or your throttle butterfly for dirt/gunk?

Just noticed that you have a 1991

Have you tried the pedal tick to get any codes in the OBC? I recon your crankshaft position sensor maybe playing up, but you will have issues with performance and MPG as well as the idle......

Its my 325i that has the problem its a 1992 the 535i is a 91

Should still work buddy

To run through the 4-digit code data on your car, put the key in the ignition and turn to the 2nd position, where all the cluster lights come on. Within a second, tap the accelerator pedal (fully) 5 times in rapid succession (total time about 3 seconds). The check-engine light will flash once and then turn off. It will then flash a certain number of times, turn off, flash another number of times and then do it twice more. If there are other codes it will then flash these. For example.... "flash... flashflash... flash... flashflashflash" would be a code of 1213 (whatever that is). If your car is telling you certain codes, you can crossreference these codes online and see if they mean anything's wrong. You will need to know the exact year and engine in your car when you search for a code list, as they differ by engine.

Gracias mate

PS, for people who think i ask this too much, go through the threads with idle issues and see how many times it was caused by a flooded or damp ECU!!

[euro325i]

Nope no rain

[euro325i]
