If your fuel injected Jeep is running rough like it has a miss on one cylinder, the trouble may be a bad fuel injector. Fuel injection is great when everything is working correctly but sometimes trouble shooting the system can be like shooting in the dark. You can’t just remove the air filter and look inside like you can with a carburetor.
I have been working with a 1989 Jeep Cherokee six cylinder recently. The truck did not run when it came to me and I did not know its history.
One I got it running, it had a distinct miss of a dead cylinder. I first checked to make sure it was getting spark to all the plugs. I did this first by using my in line spark tester. This tool flashes when the coil sends fire to the plug. All six were flashing. I then pulled the spark plugs out one at a time and visually inspected them. They all looked fine and all looked the same giving me no clue which one was the trouble cylinder.
On older engines, you could simply remove the plug wires one at a time to see which one did not make any difference in the way the engine runs. However, I have found that you can’t do that on modern electronic ignition systems as the power in the spark plug wire will give you a very uncomfortable zap if you try to remove it while the engine is running. So I don’t use that method on modern engines.

The rear drum brakes on Jeep Cherokees are generally reliable and long lasting. While swapping to disk brakes is a popular modification, the rear drums do a fine job of stopping when they work properly.
One common problem as the brakes age is that the wheel cylinder leaks. The wheel cylinder has two pistons that press out on the brake shoes when the pedal is depressed. The two pistons have rubber cups on them that will wear with age. Also, water can contaminate the fluid and cause the lining of the cylinder to rust.
There are several different wheel cylinders used so make sure you get the proper replacement before disassembling the Jeep. The cylinder for the 9″ brakes is different from the one for the 10″ brakes and the one used for antilock brakes is different from the one used for non antilock.
Begin by lifting the Jeep and supporting the rear axle. Remove the wheel and tire.

Having an accident is probably the worst thing that could happen to you and it’s something that could appear anytime. Even though you drive carefully below the speed limits or even when your car is stopped someone who is not paying attention slams into your car. Your car could also be damaged by natural disasters and you can’t predict these things.
If you want to have less worries you could always choose a good auto insurance policy but usually insurance companies solve problems pretty slow, and you probably want your car fixed and running as fast as possible. But if you need a quick solution you have to know that car repairs can get expensive and you always have to search the best repairs for your money. You should always estimate car repair costs before choosing a company that would repair your car. There could appear several cost differences for repair prices in different areas of a country and you should always pick the best choice for you.
If you have a scratched hood, small engine problems, smashed bumper or slightly damaged side skirts, these are problems that could be repaired easily and pretty cheap. But you have to know that minor repairs are pretty inexpensive, but when it comes to severe car damage then you surely have to be really careful when you estimate your car repair costs. There are some companies that overcharge you for your car repair and you surely don’t want that to happen.
A car repair estimate has six major headings: your information and your vehicle information, replacement parts needed for the repair, labor cost, miscellaneous charges, flat fees and a summary of charges. The labor cost is the number of hours spent to repair multiplied with the hourly charge of the car service. You should always check the car repair estimate to ensure that you won’t be overcharged.
