very likely your oil sending unit... just replaced mine, it would go to nothing or just float around sometimes. on my 2000 gc it was located just above the oil filter. about $42 at autozone....very easy to replace.. just unplug the wire lead and unscrew. replace new one.. but do not overtighten...... count how many turns to take it off... and use that many to put it back on... good luck... alan

#849 of 1069 2001 jeep grand cherokee laredo, changed tranny now it stalls by savahna20

I have a 2001 Jeep Grand Cherokee Laredo that the tranny went out on. I replaced the transmisson, put the transmission fluid in it and went to fire it up for a test drive. Backed out of the drive way and didnt make it 25 feet before it stalled out. Thought it was a battery issue so i went and got a new battery, installed it and started it up again. It now makes a slight ticking noise and than it acts like its gonna stall and then picked back up, does this about 6-10 times and then stalls out all together. What do I do. I am past the breaking point with this vehicle. I have been without it for 4 months, decided to fix it myself to save myself the money and it ended up costing me more than it would have cost to have the shop change it. HELP before I get a shotgun and start taking aim!

I just had to same problem on July 3rd. Driving down on a main street and as soon as I stopped, died. Turned it on. Nothing. Did it again. Still nothing. Police showed up, said 'whats going on?' I said 'when you find out, let me know". Well, the problem that we found was that the timing chain needed to be replaced. The teeth of the chain were so worn out, it cound't do its job telling the engine to start up. They are very inexpensive. My quote Autozone was for $46 and some change. The problem is the labor. That will cost you total with labor $800+. Just they have to take apart so many things that are in the way just to get to the belt. Yikes. This may or may not be a problem your having, but its best to check it out. Unfortunatly we only had the Jeep for four months and already putting just about the same amount we put down for a down payment. Hope this helps or leads you in the right direction.

My 2000 GC limited 4.7 is driving me crazy. The engine light came on so I had it checked and it came back the iac (idle air control) was bad. Thats when it started idling high, about 1000-1200 rpms most of the time. I've replaced the iac twice. I've replaced the tps. We've checked for vaccum leaks, we've cleaned the throttle body and it still idles as high as 1700 rpms and I'm just about at my wits end. Btw, most of the work has been done by an ASE certified mechanic and I think he's about at his wits end too. Any help would be greatly appreciated.

i was taking my sister to work when i heard a back fire, then looked at my guages on my rpms and mph. the mph were hoping up and down while i kept steping on the gas trying to keep the car alive. but it kept chocking and backfireing. i noticed that when my car cools off the car starts but after a while it will just turn off.
 
please tell me do you think its the fuel pump or electrical?

I have a 1997...very same issues. It started idling at above 1500 rpm, with normal idle speed at about 800. We got a code to replace the TPS so we did that. It ran for half a day and the rpm started swinging while driving it. After a few more days, the check engine light came on. We got an Idle Air Control Valve code so we replaced it. It ran ok for a few hours, then the rpm starting swinging again. There are no codes now, just a constant swinging of the rpms. When I am driving it and the rpm swings, the transmission shifts hard, both high and low. It is as if the car doesn't know how fast it is going and the fuel/air metering is all out of whack. We have had other electrical problems in the past year. Could the ECM have lost its mind? Can the ECM be reprogrammed as a check on the system? Any thoughts would be appreciated. I've carried it to 2 certified mechanic shops and they are both completely stumped as to what to do next.

Get your crank shaft sensor replaced. I had these same issues, i could drive it for a little while and as soon as it warmed up it started shutting off on me. It got to the point where it wouldnt even start until 30 mins later when it started to cool down. After 5 trips to the mechanic and 2 tows we finally got it. Hope this helps everyone
