Cant get the idle correct
Okay, my patience is running thin. My idle started running really rough and I cant get it running smooth again. I've already bought $70.00 worth of vacume hoses from the dealer (all original BMW) and still idling rough, what I mean by rough is the car is running on low RPM's and sputtering like it needs a tune up. On that note, I replaced the spark plugs and one bad ignition (#3 to be exact) and its still running like its miss-firing. I dont know what else to do anymore, now I am begining to think its the crank sensor. help me out here and give me some pointers to get my ride running smooth like before.
Thank you all in advance.
