Why is my Jeep Comanche backfiring?
Causes for backfiring normally wont change from one car make to another, backfiring in a nutshell: A backfire is when the ignition of fuel doesn't take place in the ignition/combustion chamber, it(a backfire) can take place in the intake or exhaust. It can be caused by a fuel to air ratio not being correct, also if the timing of the spark is not just right that could cause it to back fire. It could be running lean with not enough fuel and too much air, or could have too much fuel and not enough air. It could be because the intake valves are not shut when the combustion takes place, therefore the combustion would take place in the wrong spot. The most likely cause are from: 1. Incorrect timing, the timing issue could be caused by bad wiring/ or bad ignition. 2. Incorrect fuel to air ratio, bad fuel filter, low fuel pressure-caused by weak fuel pump. Most cars will have the same cause for backfiring, as long as it's an internal combustion engine it shouldn't differ...
I assume from your question that you may be looking for Comanche taillights? Since Jeep quit selling them about 3 years ago, they have been very hard to find. Due to the limited production of the Comanche, aftermarket companys have not reproduced them and they lights have actually become quite rare. If you search Jeep Comanche taillight on eBay you may have some success if you are persistent.
a Chevy 350 small block will fit into a 86 jeep comanche with some modifications. -A 350 small block will fit in a 86 comanche without modification just be prepared for a lot of work beacuse when you do that the ENTIRE driveline needs replaced all the way back to the knuckles on the u joints at the differentials. you will also need to adjust the motor mounts. but nothing significant.
