the stig 0 Report post Posted November 24, 2008 Just trying to get a few things sorted out on the 325i When you rev it up and let of the accelerator, the revs drop below normal idle, neraly stalling the car, and then go back to normal idle again. Its getting a bit annoying becasue it stalls itself at intersections etc Cheers for the help Nick Quote Share this post Link to post Share on other sites
greenday-rulz21 6 Report post Posted November 24, 2008 ICV I would guess. In the e36, if its clogged, it causes surges at idle. A common problem, and a pretty easy one to check. Quote Share this post Link to post Share on other sites
Cale 36 Report post Posted November 24, 2008 ^^ I agree. I had the same symptoms as yourself and it was a dirty ICV. Quote Share this post Link to post Share on other sites

bmpower 3 Report post Posted November 24, 2008 Could also be the rubber hose going to the throttle body from the airbox. It may be split. This happened with mine, which was split where the hose clip goes. Quote Share this post Link to post Share on other sites

On the ICV, do you just mean the plug that plugs into it? Quote Share this post Link to post Share on other sites
greenday-rulz21 6 Report post Posted November 24, 2008 On the ICV, do you just mean the plug that plugs into it?No, the actual valve. It gets clogged with sh*t and gives an uneven idle. Cleaning it should improve idle even if its not the thing causing your problem. Quote Share this post Link to post Share on other sites
