Question about 1999 Jeep Cherokee

2 Answers

Hi, I have a Cherokee 1999 sport and right now, when I start the engine and walk for about 10 minutes it becomes unstable, like if it would want to stop, and looses power, after trying to accelerate a lot of times, suddenly runs good again, and after a few minutes it does it again. it happens mostly when I´m going up. I´ve allready changed the fuel and air filters, What could it be? Thank you for your time.

    Thank you very much for your comment I was thinking about the same posibilities too, but the problem is that the check engine ligth doesn´t turns on, in fact, when I start the engine the light turns off normaly. again thank you for your help

    Again thank you very much for your comment. I´ve allready checked the distribuitor cap, rotor, spark plugs and cables, everythig seems Ok. I was thinking if it could be a gas filter that goes inside of the tank, it is so thin that it might be covered with dirt. I´ll replace it and post whatever happens. Thank´s for your time.

Ask a local mechanic to have a look as too many variables here that could cause this

    1999 these vehicles still used a distributor cap ,take it off and look at the carbon brush in the middle and signs of tracking ,if it appears ok then suggestion one ,ask a local mechanic but please post comment so someone can confirm that this would or can cause the problem .

My 1999 Jeep Cherokee Sport acts like its running out of gas all the time stalls when it gets hot it starts back up again when you let it cool for 10 minutes

If it has the 6 cyl engine, a very common problem on higher mileage engines is the crank sensor located in the top of the transmission at the back of the engine on the drivers side

How to fix 1999 jeep cherokee sport

You mean it cranks but does not start, right ?
The NoBus on the display means the cluster is not talking to the computer. That could be a wiring problem or a component problem.
Have you checked the engine computer for trouble codes ?

It sounds like it needs to be tighten a little. I can remember if this has a belt tensioner or a regular manual tensioner. If it can't be righted as long as the belt is not cracked or damaged you can add a little silicone to both side of the belt. Just a couple of fingertip dabs. This will quit it down. Make sure the engine is off or battery disconnected to avoid injury. Also if this is a self adjusting tensioner that usually is a sign that the spring tension is starting to decrease.

Have you looked at the crank position sensor? It's mounted on the transmission bellhousing, on the right side of the engine near the top. It's a relatively cheap part and is fairly easy to get to.

Wait a minute, when you say "small amount of white smoke from the back of the engine," do you mean under the hood, or out the exhaust pipe?
