20 Most Recent 1993 Jeep Grand Cherokee - Page 2 Questions & Answers

is it all time 4x4?

Have a shop look into this and repair it the right way, stop throwing pumps on this, do it right find the route cause.

I don't know engine size? The fuel pressures I found was 31--39 psi, 92--95. I would use a gage and check proper fuel pressure. How long since over-all tune-up? Any applicable trouble codes?

Sounds like the track bar is worn out

is this a how to diagnose it question or a kids guessing game. we can guess all day, even all week, your CALL ! 1993 still running a "Kodak moment"? wow. that is called MISFIRE, there are over 50 cause of that. are you going to guess up to 50 + times> ? id hope not. and all misfire causes engine power loss, (all) ZJ jeep 3 engines, 5.2L is yours. ever put in new spark plugs??? in last 10 years? you cant burn fuel with bad spark so this is like #1 for 100 years+ gas engines.... test 1, can you save the stall, with a fast right foot if no, the you lost 12vdc to key EFI parts or its fuel problem this be 2nd after new spark parts, (a tuneup is always first of owner does NOT do proper service) why spend 4 hours shop labor only to find , omg,100,000 mile old tuneup parts, (big cash to learn they dont last a life time)??? TUNEUP? filters (both) spark plugs. if those old ratty spark wires are 24years old, they are hopeless distributor cap, same thing distributor rotor same. if it still misfires, it can be injector problems. (lots of tests here) even engine cylinder compression low, we always check 90s cars for this, after all its OLD. generic, data; on 5.2. 9.1:1 CR sea-level spec only. 150psi x8. wide open throttle or more. read data shows 1993-1998 Grand Cherokee. 5.2L v8 9.5:1 CR, 180 PSI ask how to do that test correctly. This 1993 the check engine lamp can glow, running? if it is? , it must be scanned to find the codes, DTC errors Innova 3160 tool can do that. or most good shops. or even the Actron CP9145 (used onlY) the latter tool is the Bee's knees on old cars. with EFI.

ever do a real tuneup this decade spark parts, and filters. that be first and make sure the hot engine (sized not stated) is really hot. 180F or more, and holds, it must reach normal spec, temp. or the ECU brain will not do its job right. the only clue I have here is skips skips must mean misfire. there are over 50 causes of misfire. bad spark plugs tops the list. and all spark parts there, cap/rotor,wires set this OLD. car is old , needs a major tuneup they to forget all that other stuff, and elaborage what skips means. i guess never cold does it skip. taCH DROPS TO ZERO BUT engine not heard to stall? if yes, electrical problems or CKP failing? what does engine do when TACH does that, matters big time.

In the old days speedometer use to have cable today's cars n trucks have a speedometer sensor on the out side of the transmission there not hard to install just google on line it tell how n where it is good luck

Do you do any testing before you replaced computer? Why did you replace computer? Did you check trouble codes before you replaced anything? If your missing fuel--spark and fuel injector pulse, I'd have to check for rpm signal. On this vehicle, you may need to check cam and crank sensor both. Hopefully you can get some mil codes, but after replacing computer, I don't know? To get mil codes, you can try cycling the ignition switch, on--off, on--off, on--off, on, then the mil on the dash starts flashing, you count the flashes to get the codes. These are two digit codes. I have to post basic info because nobody ever tells us what kind of testing they have done? Listed below are some of the codes.

Replace the bulb ! Refer to you tube !

It may be over filled ! If not Try You Tube ?

the first good GC... 93, and a good start. but is old i read that 3 times, and draw a blank, try to tell what works an dont, tottally like what your mechanics sees, he sees all. all things good, bad and ugly, all at once. there are key fobs and there are door on door locks. and not just one.

remove the door trim and adjust the window channel inside the door if the felt lining moves with the window it probably need replacing adjust the channel with the window down or it will jam as the window comes down
