Car Forum / Driving, Maintenance, Tuning / General Car Topics / February 20061985 BMW 318i will not idle properly (HELP!)
I recently aquired a 1985 BMW 318i. It will not idle properly. When the engine is not in gear and moving, the engine will jump constantly between 900 and 1100 RPMs while idling. Everything else seems to be running properly. Someone told me that the idle control unit needs to be replaced. Do you think this correct? I have heard that there is an idle control valve; this is not the problem? I cannot locate the idle control unit. Someone told me that it is located in-between the glove box and dash, but I can't find it. Will someone provide me with detailed instructions or a diagram? I cannot afford a mechanic and am not savvy with cars. I cannot afford a manual, but wonder whether or not this information is provided in the Bentley manual. Ouch, folks throw those away up here because unless you/they are a sharp mechanic, they are WAY too expensive to fix or own. Now if you have just won the lottery you might be able to keep up with the repair bill.... If the mechanic really likes you... Idle jumping sometimes or usually means a vacuum leak is happening. A loose oil dipstick can cause it. There are other vacuum modules that can fail and cause an idle surge, but I only know for sure the loose dipstick will cause it because I 'fixed' one like that after my brother in law spent $2000.00 at the 'mechanics' trying to make it run with only the mechanic's wallet the winner.
