It maybe bad gas or just water in the lines ! Try some dry gas ! And do not let your fuel get so low . Never less than 1/4 tank or you run the risk of burning up the fuel pump ! As the pump uses the fuel to cool it ! Check it out on you tube !

How do I stop my Jeep Cherokee from Bucking down the road?


first off what is bucking? you never said, (engine or trans)????
there are may parts on the car, that can buck, shake, or surge.


the jeep keyon off on trick usually is totally useless for this problem. but heck free to try.
the problem here is the ecu forgets some error after keyoff. oops.. you need to scan it using a real scan tool....

if savvy and like danger
try to see if the asd drops, at the buck moment.
there are ways to do that. ask.
(bad dealer, fire him) try an honest , ASE shop and mechanic.
google "ase shops" BINGO !

avoid stealerships and only as a last resort. (a ride to h3ll?)
for that cash could buy a running used one. here.
it's an old jeep, and like all old cars they will be a problem.
all old cars are.
I'd have a scan tool connected, my INNOVA 3140 (does old jeeps)(this tool does old jeep OBD1 scans)

and see what codes are stored, DURING the buck.
that's right driving and scanning, wife drives, you scan... or?
if it's the engine, it will show something,.
ill guess, now,.... (useless)
1: engine bucks, actually its stalls and recovers.
the jeep has a THING, called ASD.
if the ASD drops driving it WILL BUCK, and is clearly not transmission slip, or trans gear shifts caused.
its engine, so focus on the ENGINE and EFI system
if you lose to fuel pump pressure its not a buck its a slow bog.
so its not the pump dropping off line.
its spark dropping. and the ASD does that on purpose.

read this.

what is something

if the ECU loses power, 12vdc main power,
the ECU goes off line and the scan tool shows. (lost comm)
bingo, no?
or if not that the ECU reports ASD related EVENTS (DTC'S)

94 grand cherokee cutsoff going down the road then won't start until it sets for a while


When it won't start someone will need to find out if you are dealing with a no-spark or no-fuel problem to proceed.
If the check engine light is on you should get the computer scanned for trouble codes.

97 Grand Cherokee larado dies when you slow down or are stopped. Some bucking/stalling when driving it. We have replaced trottle sensor and igination coil; change air filter; but we did just install a new...


The ac compressor does put an additional load on the engine.
Any minor problem with performance can be amplified with the ac on.
I would check fuel pressure and look at the idle air control valve.
Also check the computer for trouble codes.
Both 6 and 8 cyl engines use a cap rotor and wires arrangement, so it wouldn't hurt to make sure those components as well as the spark plugs are in good working order.
The bucking on the road and stalling at stops could be two different issues.

94 Jeep Grand Cherokee will not start


Sounds like the inline fuse popped. It is located in the wire that comes from the alternator to the battery. The alternator is sending out the juice, but it can't make it to the battery. I sincerely hope that this gets you on the road again. Best wishes and God Bless.

Bucking problems with a 94 Jeep Cherokee


if you have not put a fuel filter on yet i would, and then do a fuel pressure test. if filter don't help and pressure is wright, might be water in fuel. do fuel filter, pressure test, fuel additive, might be cheap fix. if what i said don't work, and everything else checks out ok, then the only thing left is fuel regulator. but also don't loose sight of it being electrical too.
