Top 20 1988 Jeep Wrangler Questions & Answers

You have an air leak around the throttle body

Start out by checking the latch mechanism on the door. Use a screwdriver to "trip" the latch with the door open, then pull on the screwdriver against the latch gate. If it doesn't hold then you may have a bad latch (the springs in the latch can go bad over time). You can also try spraying penetrating oil (PB Blaster) into the latch and again using a screwdriver to trip the latch, then open with the handle, and repeat several times to work the oil into the mechanism and free it up (this trick also sometimes works with the springs on wiper arms that have lost tension). If the penetrating oil trick works, think about spraying dry lube or white lithium grease into the latch to help prevent it from happening again. If the door is misaligned, consider new hinge bushings, a misaligned door can cause damage to the door, and put tension on the door latch in a direction that puts pressure on the latch that it wasn't designed for.

I hate to tell you this but... If it overheated you probably have at the very least blown a head gasket. The best thing to do is run a compression check and that will tell all. Hope that helps

richard is right what ever has happened after you played at being electrician Put it all back to standard then get advice as to how to do each part

Did ya blow a fuse while working on it

both stuck mid glass?, not stuck running endless when off,? that means the auto park switches in the wiper motor guts are bad. when you turn them on the motor self runs, the runs until the keep alive contact cam reaches the end ad self turns off in park. that cam fails on all 1988, its old. and hopeless that old. if you had dismantled it youd see DAMAGE on the cam contacts or the wiper brush to it.

Could be the starter motor, a bad solenoid or bad battery connections.

cec.timing of what, cam or spark.what engine, is there. Computerized Engine Control or Computerized Emission Control (CEC) the 4.0L and 2.5 liter , uses the RENIX ecu. and not the CEC. tje REnix has fixed, CKP sensor timing.the 4.2liter has distrib timing.see below.my guess is you have the instructions andget lost at the find VACUUM switch on top of valve cover words?yes?

Hi there Tap the starter motor and solenoid with the wooden (handle) part of the hammer to loosen the internal workings, a possible layer of rust formed on the inside of the starter. Regards Phillip

Your catalytic covertor has basically disintegrated and is blocking the flow of exhaust gas from the motor causing your lack of power. You need a new convertor

Front main? Rear main? Trans main? Diff main?

how low,PSI?

If it's stalling out at times did you check the crankshaft position sensor? That usually happens to Jeep vehicles a lot for some reason or another.

take feed from the fuse box, but always put an inline fuse in. Do you know how to use a test light? Most fuse boards have a spare Perm live and Ign live. Cheers Roger

old dog , jeep, sure. its a PART TIME 4wd, not AWD. you post but forget (100s like this here) with no road surface stated. dirt, ice, snow, off road, pavement. what?? my wild guess, is this car is new, to you, and you never read the operators guide yet. lost 25 years ago, but sold on fleabay PT-4wD do not drive on pavement dry , or you WILL wind it up. WHEN I SAY 4wd I MEAN , the front lockers are locked AND the transfer case is in 4wd.

You could have two different problems . I have had two 1999 wranglers an the dash panel going out has always bin a faulty main connecter to the panel . I reach up under an wiggle an push it back in place . It doesn't come out it just loses connection . The other problem is a faulty dimmer switch i think .
