God's Chariot. The E30 was produced primarily from 1982 through 1991. The cabriolet was the one exception which was produced through 1993.

idle problems

Hello. i was just checking if any of you guys can help me out with a problem I'm having. I have a 91 318i E30 and it won't idle. i can give it gas and its fine but once the rpms drop it sputters and dies. i recently changed the timing chain tensioner to get rid of the knock i was having. i was just wondering is it something to do with timing, maybe something jacked up in it before i put the new tensioner in or could it be the idle control valve or something that i'm not aware of. it actually idled good for a good minute then i gave it some gas and when it went back to idle it started messing up again. any help would be greatly appreciated.
thank you

Eric

Sounds like a faulty Throttle Position Sensor. When the accelerator is not pressed, it will tell the computer that the car should be idling, which yours doesn't seem to be doing. Its part of the throttle body. I accidentally left mine disconnected once and had the same symptoms.

Was the Throttle position sensor (TPS) your problem? I got the same problem going on here and I suspect the TPS.

i hate to say it, all vehicles that run obd have tps. all those cars can have the same issue.

but on the other hand, have you adjusted the idle via icv? mine started to act up, and i fixed it that way
