I am trying to sort out a rough idling problem on a friend's car. The car was running rough and she took it to service, where they diagnosed a faulty Crankshaft position sendor. After replacing it, she is having the car idle rough. Right ater it starts it seems OK for about half a minute but then it
will sound as if it is missing a few beats. I took out the fuel rail and all of the injectors deliver fuel, although I cannot tell if the pressure is right (haven't worked on a Jeep before). No vacuum leaks either. I checked each vacuum connection by plugging it and there was a noticeable change in idle speed.
I also noticed that the car hesitates if one tries to accelerate hard at speed
(e.g on 4th or 5th gear - it is a manual). I am thinking faulty throttle position sensor. Any suggestions?
