Recently when i would start my car up from a cold start, it would fire up right away but right after the car would jerk about 5 times or so and then smooth out. I revved the engine and when i let off the throttle the RPMs would drop dramatically and then it would recover fast as well. It usually does this after i wash the car and it never does it on a warm start.
any ideas what this could be?
