Check the scanner and see if the oxgen sensor is fluctuating up and down on the voltage.
If not then the sensor is bad.

1999 cherokee starts and runs fine then idles rough and dies


If the start and run fine are on cold starts, I would look for vacuum leaks. The normal start mode for these things is to have a richer condition upon a cold start. When the ECU detects warmth in the engine is drops the extra rich cold start mode then the idle goes rough due to the normal mixture being too lean due to a vacuum leak. Look for cracked, loose or broken vacuum hoses. It could also be due to a EGR valve stuck open.

My sunroof is stuck open on my 1999 jeep grand cherokee laredo? Would it be a fuse? If so, how do you change it?


Definitely, you'll have to take a look to see if any obstruction is visible. To check the fuses first you'll need to find them. The fuse block cover should illustrate what each fuse is for. You can visibly check the fuses, with a flashlight. Just take a look at the sunroof fuse and check that its not burned. That the metal inside goes from one side to the other and its not burned or broken. You can use a test light or a multimeter, a test-light will do. I usually check them visibly, its obvious when you have a blown fuse just by looking at it. Its better just to pull out the suspected fuse to check it.

Check the fuses under the dash on the drivers side, next to the steering column. There should be a fuse puller on the fuse box door. Also a chart of which fuses at what so you can go to the proper fuse. Good luck, Please let me know if this is the solution to your problem.
