Question about 1999 Jeep Grand Cherokee

1 Answer

Jeep will not hold an idle. Just wants to die.

I have just replaced my computer in my 1999 jeep yj, (Its a YJ not a cherokee), and the same thing is happening as before. It wont stay running. Difficult to get it started. Everything else works. ''Check engine'' light comes on. With the old computer the gas guage didn't work, but now it does with the new computer, but it still wont stay running. The new computer that I got for it is a rebuild. Is it possible that the new, rebuilt, computer needs to be reprogramed, or can I just hook it up and go? Or is the problam else where?

Check your engine to see if ,it has a yellow or blue spark and if it does then check your fuel filters and fuel pump to see if they are working or not.

As to the 1990 Jeep YJ I asked about,engine is running, starts and idles fine. When you try to accelerate, acts sluggish until engine starts to warm up, then runs normal. Have changed the temp sensor.


Have you done a complete tune up ? To include replacing the fuel filter ? Are you the original owner of this Jeep ? If no, may have worn engine cylinders, piston rings, or bad valves. Many things could cause this problem.

88 jeep yj carb 6 cly automatic, where is the map


If you have a carb you do not have a map or IAC valve. They are on fuel injected throttle body setups. You really should go to an auto parts store and get a book if your really interested.

1992 YJ can only shift into 3rd & 4th gear. No Reverse


The same thing happend to one of my wranglers, a 95 yj 4cyl 2.5 liter. The "Aisin AX-5" is the transmission that jeep used on the yj and tj 4cyl and 83 cherokee and up 4cyl, and the "Aisin AX-15"was used on some of the 6cyl models. Both are a "light duty" transmission according to the transmission manufacturer. As everyone knows, A jeep is no light duty vehicle, the shifting slider, a fork like item slides the gears back and forth over the drive and output gears to change the gears. and with heavy use or lack of maintanice they can break, they also can break cause of the cheap casting they used in the tranny. Other problems happen in those trannys too. The only thing is to tear the tranny apart and find out what failed and replace. I did this on the kitchen table ofer a day off. being the up own an early 90s yj, If you are one who doesn't work on their own car, I would find a good garage that is good with jeeps, they are not to expencive to fix, and when they are taken care of, will be a joy to own.
I hope this helps, Jeep ownership is a great thing.
