Shudder and surging idle
Hi All,
Problem with my 2007 335i. Just hit 91k and had it serviced, new plugs and oil. Follwing that, the car feels better and pulls harder above 4k. However at idle after a while when the engine is at temp it will shudder then the revs rise to 800 and stay there until i turn it off and on again. Then if i drive all is fine. All the common problems have been replaced, camshafts, ledges, vanos solenoids, vanos gears, hpfp, turbos, radiator, water pump. Im really at a loss at wht could cause it and the car isnt coding at all. Any ideas? |
