I have a 1997 Wrangler SE. 4 cyl. Driving around town, I don't notice any problems. If I drive 100-150 miles in one direction at one time, the Jeep starts losing power, then it begins "missing" or acting as if it isn't getting fuel. I doesn't quit, it just "misses." I took it to a shop back in June, they ran a diagnostic and said it was the MAPS sensor. I also changed the cap, rotor, plugs, and wires and it ran great until earlier this week. It jsut started after about 150 miles into a trip from Boise, Idaho to Salt Lake City, Utah. The diagnostic shows nothing. Anyone have any ideas? Thanks.

Would that be before I-84 meets I-15? Some parts of that route may take you over 6,000 feet in elevation. Could the reduced air pressure there affect manifold pressure?

That is exactly where the trouble began. Just about 20 miles before Snowville, Utah. Then it continued sporadically until I got home. I suppose the change in elevation could be affecting manifold pressure. It could mean the MAP sensor installed back in June was faulty. Any other thoughts? I'm headed to Autozone this afternoon to see if they can pull any codes. Thanks.

That's all I can think of off the top. Any other Wrangler owners experience those symptoms?

Autozone is unable to run a diagnostic unless the check engine light is on. So I took the opportunity to stop in at Terraflex (formerly MEPCO, all Jeep, all the time...) in Salt Lake and I had a chat with the head service tech. He 99% certain that because nothing is activating the check engine light, I have an injector going bad. Once I run for a while, it heats up and aggravates the bad injector. He says he'd put money on a bad injector causing the occasional single cylinder misfire. This weekend we'll run a diagnostic history to find the misfiring cylinder, replace the injector, and according to Terraflex, I'll be out the door for just over 2 bills. I'll post the rseults for future reference. Thanks.

#670 of 1886 Why can't we get pressure back after replacing the brakes/rotors/calipers?? by glenswife

Replying to: tidester (Oct 18, 2006 7:33 pm)
Last week I took my 97 Wrangler in for an oil change and found out that my front brakes were metal to metal. Lucky girl that I am my husband is a mechanic so instead of paying someone else to replace them, I asked my husband to do it for me. Well, he got the new rotors/pads/calipers on and then I did my part by helping him bleed the brakes. For some reason after bleeding the brakes we still weren't able to get pressure back in the pedal when the ignition was turned on. My husband ( a few expletives later) thought that maybe the master cylinder needed to be replaced so we did that and still no luck. A few months back he had bought and installed a remanufactured master cylinder on his brothers truck that ended up being defective so we thought that maybe that was the problem. SO, I took it back and picked up a new one yesterday. So here were are we new rotors/calipers/pads/mastercylinder and no pressure when I push on the brake pedal. At this point my husband is absolutely frustrated because he is a mechanic and feels totally incapable at this point because this was such an easy task and it still isn't complete. Has anyone had a similar problem with their Wrangler? Any suggestions on what to try next? Thanks

I suggest asking your question in Stop here! Let's talk about brakes or Jeep Wrangler: Problems and Solutions and the main Jeep Wrangler discussion may also be helpful.

When bleeding the brakes did you start with the brake the farthest away from the master cylinder? Did your husband bench bleed the master cylinder before installing it?

Yes, we started with the farthest, working our way to the closest. I'm not sure what you mean by bench bleeding the master cylinder. Could you elaborate?
