| 325e IDLE PROBLEMS
*btw, your ICV should be humming with ignition ON(it's a DC motor) inside that sucker, and if it isnt humming, then it is dead... or the voltage supply line is dead.
I did realize that my 525I idle control valve hummed while ignition was turned on. and I had to replace the ICV on the 525I once. But on the 325e is does not hum while on, and when electrical hook up is disconnected it changes no characteristics. Idle is erratic as of now, reving up to 1300 and then dropping down to 700-800.
I believe the ICV is fine.<<<but may not be. have done all fuse tests and intake has no leaks. i do believe it is a electrical problem. <<<referring back to a previous thread I wrote up. QUESTION what is the remedy for replacing the voltage supply line to the ICV???? |
