Check fuel pressure, change filter if delivery is low, change pump if pressure is not right after filter change. There could be more problems but that is where to look first.

1993 Laredo. Does it have two fuel filters?


are you on wrong forum, Grand cherokee is it?
the XJ jeep is not a ZJ jeep. which is it, the big GRAND ZJ?
what a great question, actually cars with EFI all have 3 filters...
sorry to shock you.

1: the fuel sock , below the pump , to catch loose golf balls. LOL.
dead bugs, etc.
2: the pump output line has a filter., all do, can be in tank (newer cars) or just outside (did you look first or post first) bingo!
3: then each injector has 10 micron size screens. the above keeps these clean, saving $120 for injector service and labor R&R.

and what engine, not posted engine size on engine questions
the fuel system matches ENGINE type, on all cars made.
4.0L engine ????

ive owned both a grand laredo and not grand laredo 1988 to 2010

if not grand see this XJ car.
called just a Cherokee here. 1993

The rpm of my 93' jeep grand cherokee,changes from 2,000 to 3,000 rpm,when i'm driving at 70 mph, it does this 3 or 4 times in a minute some times it doesn't do it ' i've changed the tps and it still does...


have u run a fault code test on the systems computer, this sounds like maybe a Vehicle speed sensor problem, the speed sensor is on the side of the transmission, but do the code test, here is how u do that, go to the link below for instruction's that apply to all Chrysler cars and trucks

1993 jeep grand Cherokee...stutter in drive at low rpm


Hello;
Have you checked your fuel pressure and volume? You may not be getting the ful sufficiently to the injectors. Also, change your fuel filter if you haven't already. Is the check engine light on?
Thanks;
