1999 BMW 528i - Acceleration and Lagging
I've recently had a problem with my beloved 528i....a few weeks ago it started seriously lagging and taking off very slow. When I accelerate, the car takes off really slow. Once it changes gears everything is fine and the car drives great at highway speeds. However, once I stop and takeoff again, it does the same thing.
The check engine light was on and showed a P0340 code (camshaft position sensor bank 1, single sensor). I replaced both the intake and exhaust CPS (Bosch parts) and the problem went away for a few weeks. Now it's back again.
Tomorrow I plan to change the Crankshaft position sensor, replace the valve cover gasket, fuel filter, new plugs and boots, and change the oil. If the problem persist, I'm going to replace the sensors again.
Has anyone else had a similar issue. This is driving me nuts. I have a long trip in about 10 days and need this car is tip, top shape.
