cummins missing a beat?
hey guys, just wondering whats causing my truck to have a rough idle after coming to a stop or after reving it up. it almost sounds like its missing a beat. if you let it idle for a little bit like 30-45 seconds it smoothens back out. other then the idle issue it runs the nut. cleaned the iat, and map sensor thinking it would help, and nothing.

i check the fp. with engine not running, but lift pump running its 19.5 idling its 16-17, and when revved it drops to 14-15 range. so i dont think its the lift pump. gonna change the fuel filter soon and see what happens....
