Engine Problems
Last week I started my 335i e90 and it started shaking like crazy, the rpm was jumping and the service engine soon light was blinking, after reading it on impa, cylinders 4,5,6 were misfiring so I changed the plugs and coil packs. Everything seemed to be o.k. yersterday morning on a cold start as well samething happened. cylinders 4,5,6 misfiring with the same shake. Its weird cuz after ten minutes with the car on, once I restart it, the light doesnt blink and the idle is fine, everything is perfectly normal. The codes I received both times are 29D2, 29D1, 29D0, and 29CC. The car was manu in 06/2007. Any suggestions, please help

If no codes are being thrown use Chevron Techron fuel injector cleaner (concentrate). It solves rpm fluctuating upon cold start-up. Also, for most BMW problems start off by scanning your car with the Peake Research Tool. It contains the actual BMW codes. If you want to register a newly installed battery for free (just buy a $10 cable) and google/download BMWLogger
