SOURCE: My Jeep overheats while sitting idle. When I drive, the gauge goes down quickly. I have had thermostat and fan changed. I have also had the radiator flushed. What can it be?

we have a 2003 and it did the very same thing . Its called cooling fan relay it costs about 60.00 and is located behind the headlight assembly . not very hard to fix if you know anything about cars .

Thanks for choosing FixYa and welcome to the site. To be honest with you, there are many things that can cause a rough idle and power loss. I will tell you everything you need to check. Check to see if you have any vacuum leaks. Make sure your air filter and fuel filter are not clogged. If you haven't had a tune up in a long time, you need to have it done. Change your spark plugs.coils, wires, distributor cap, coil packs. Change your fluids if possible as well. You want to make sure to check your pcv valve also. Inspect all wires and hoses to make sure they are not damaged. And lastly, make sure the battery is good and holding a proper charge. Make sure the terminals are cleaned. If your parts are not getting the proper voltage, your vehicle will not perform like it should. If you have any questions, feel free to ask and thanks for using FixYa.

The Jeep was running fine, then just started shutting off. Then It ran rough and shut off. Replaced the ECU as recommended by a mechanic. Jeep will start up and idle for a few seconds and then run rough...

Have you checked the crankshaft position sensor. It is on the bottom forward part of the engine, real close to the hub for the fan. It has a wired plug leading to it. It tells the ECU when the number one piston is at top dead center. It needs this signal to stay in time. It sounds like it may be going out.

Just bought a computer for 1994 jeep grand cherokee but have no clue how to install need info to plug in computer

First, disconnect the Negative Battery cable. Your "computer" or PCM, is located behind the Coolant Recovery Jug on the Passenger side Firewall. Remove the two 10 mm nuts and one 10 mm bolt, and swing the Coolant Recovery Jug out of the way. The PCM has 3 connectors. Going from left to right, as you look at it, the connector's colors are as follows, Gray, White and Black. Remove them, remove the old Computer and reverse the operation to install it. AFTER every-thing's complete, then hook the Negative Battery Cable back up and start it.

1997 jeep grand cherokee... missfires... idles rough when stoped.

hi there, sounds like a bad fuel pressure regulator. a bad regulator will cause it to misfire and idle rough. also does it run good at higher rpm if it does i would be 80% sure that would be your problem
