racing idle

[jordano]

I have an 89 320i and it seems to be very racey when idling, but only when iam short on fuel, any ideas?????

Dont let it get low on fuel!!!

Thats a bit bizare mate as the fuel is regulated to 2.5 bar regardless off amount of fuel in tank.

Usually High idle is caused by a sticking ICV or throttle linkage etc

dont if i wrote it correct, what i mean is it is racing up n dwn when idling sometimes to the point of stalling
