What is the proper timing degree for a 92 jeep wrangler 4.0l

most cars will not pass emissions with out them. some places may also want the catalectic convertor on the car.

sounds like a head gasket problem....is your anti-freeze reservoir pressuring up as well?

Is the cooling system full ?
Have you changed the thermostat yet ?

Ignition timing is a measurement, in degrees of crankshaft rotation, of the point at which each cylinder's spark plug fires. It is normally listed as a specification in degrees before or after Top Dead Center (TDC) of the compression stroke.

On the 4.2L engine, the timing can be adjusted by turning the distributor in the engine. A graduated timing degree scale located on the timing case cover is used for reference when timing the ignition system. A milled index notch in the vibration damper is used to align the No. 1 cylinder ignition position of the crankshaft with the correct timing degree mark on the graduated scale.

Hope this helps; also keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using Fixya, and have a nice day.

Sounds like there is a bad conection at the starter
under the left side of the jeep you will see the starter its is by rhe oil pan on top there is 2 wire conections see if it is looose here.
if your going to snug the eire ends up disconect the battery first

sounds like possible timing problem ( chain and gears or distributer or ignition wires )

the wiper needs to be tighten some more, there is a nut that holds the wiper to the motor tight that nut.

The thermostat controls operating temperature. This occurs at a preset temperature (typically 195 degrees F. or so), which is usually stamped on the thermostat itself. The thermostat should be fully open about 20 degrees F. above the rated temperature. So your operating temperature is about right. If you have doubts, just replace the thermostat with a new one of the correct temp.

With high altitude emission


9 Degrees Application: With manual transmission

i found in my jeep the parking brake likes to freeze on in cold weather other than that it sounds like it could be tranny transfercase or axels seized
