Question about 1989 Jeep Wrangler

Open Question

How do you reset the emission maintenance light? I have a 1989 Jeep Wrangler with a 258 6 cyl with 65000 miles. It passes Utahs emission standards with flying colors. The shop said it comes on at 62000 miles They did not know how to reset it. Or do I have to take it to a dealer?

It's a module under dash programmed to turn on Maintenance light. You can pay $80 to replace module or pull wire going to module and save $80. BTW, it's there to tell you to replace your Oxygen sensor.

Yes you can. You would have to get the correct tranny for it and all the linkage to the tranny and the floor shifter. You should just keep the manual tranny. It will serve you better and for more miles than an automatic. The cost to switch to an auto would not be worth the price. Most people would rather have a manual in a jeep if they use it for it's intended purpose.

SOURCE: "maintenance required" light is stuck on in 1991 Jeep Wrangler

On the dim dashlights, there is usually a rotory switch that you can turn to increase the power to the dash lights. In earlier vehicles it was part of the headlight switch and you just turned it one way or the other to adjust the brightness. In newer vehicles it is a switch like a knob sticking out of the dash on its side that you push up or down to change the brightness of the lamps.

The Maintenance Required light is probable on because the vehicle has hit the 50,000 mile mark and it comes on automatically so that you take the vehicle in for maint. of the emission system. If this is the case there is usually a way to reset it untill another 50,000 miles go by. I would read the owners manual, or better yet pickup a Chilton manual for the vehicle and see if it says how to reset the light. You also may want to have the vehicle checked to see if any trouble codes have been signaled. Good Luck, RAC

Emission light is on


Have your diagnostics checked, it could be the Oxygen sensor (O2). This is common if your vehicle has a lot of miles. Another cause, and more expensive, the catalytic converter could be on its last legs.

What should the idle speed be set at on a 1989 jeep wrangler 4.2 liter straight 6 cyl. It has a 2bbl carb. It idles at 1000 rpm right now but seems fast or is that about right?


Most carb. engines should idle between 725 and 750 R.P.M., lower the idle and be sure to check the timing. You should have an emissions label under the hood to explain the idle and timing.
