Having problems with your 1999 Jeep Grand Cherokee ?

Hitch in engine

\015 Intermittantly, when I take my foot off the gas, there is a slight hitch in the engine. This happens mostly when I am going slower - under 30. I haven't noticed this at faster speeds. Any idea what is causing it?\015 Posted / edited by AnonymousUser on : 30-03-2020

Answers :

If the "hitch" is minor, likely it's due to a sticking control valve\015\012somewhere...You could try some injector cleaner or manually clean the\015\012throttle body and see if it makes any difference. Could also be a small\015\012dead spot in the throttle position sensor. When problems are small,\015\012they often don't set codes because the fault does not meet the\015\012computers requirements to set one. Most larger parts stores will do\015\012free code testing though and you may want to have a scan done just to\015\012see if anything shows up. Problem could also be caused by a delay in downshift of transmission in which case a fluid change may help. This is where an experienced tech becomes most valuable...just test driving, the problem usually can be isolated to engine or transmission...No one here can feel the problem, only read about it, so the best suggestions may indeed be correct but not correct for your problem.
good luck
