Any ideas, port engine shuts down, will start back up at a high throttle but stall when the trottle is backed off. Could this be a typical IAC valve problem? Thanks
I think I might have the same problem with the port engine on my 2004 340. It cut out on me on Lake Ontario. Had an AOU alarm go off. Could restart the engine but would stall as soon as I backed off the gas. Mechanic thinks its a Mass air-fuel solinoid, but sounds more like the IAV valve to me...
