I have a 96 Xj and when i press the pedal hard out go to pass someone my Jeep bogs down pretty bad and it won't go any where she's fine if i baby here. Also weird clunk noise from drive side wheel area when I get on her in the mud also boss down while doing this. could my alternator make it run like this they said it was bad.

 

As far as the clunking sound in the front I would look at the axle u-joint to see if it is broken. The bogging down under load could be the TPS or it could be a fuel pump starting to go.

 

Cool thanks I'll check it out. Also the bogging feels like it's a manual and i can't drive lol

 

It wouldn't hurt to check your transmission kick down cable. It attaches to the throttle body next to your throttle cable. If it came off then it won't downshift when you mash the gas.

 

All the cables seem good on throttle body.i took it off yesterday and cleaned it pretty good. I've been doing research and ppl say it's o2 sensors or tps but i wanna make sure before i dump money. I'm already going to do an ignition upgrade kit i just don't know which one right now more focused on accel

 

It only happens in acceleration runs and idles okay so far also changed oil has bad tick/knock. Better oil?

 

So i changed the tps and it doesn't have a weird idle anymore but it still sucks on acceleration when i get on her it just doesn't wanna go for a few secs then she'll take off. So idk, any other ideas, i figure o2's

 

Couple things come to mind... Possible jumped tooth on timing chain or possibly low fuel pressure...

 

you might also want to check out IAC valve. if you are having a hesitation it could be coming from there too. Try to clean it real good with some carb cleaner.

 

I second the fuel pressure test.

 

Did you adjust your TV cable? Engine off, press the D-shaped button and push the cable housing all the way in to the adjuster. Release the button and twist the throttle to wide open. You'll hear the adjuster ratchet as it self adjusts. Test drive. It can be adjusted a click or two (longer or shorter) for faster or slower shifts, but if it's off by too much, your tranny can be damaged. Hope this helps.

 

This is free to do if trannys not down shifting .

 

I will try this after work. I wanna throw in there tho that it bogs down a Lil when I'm coming to a stop just for a sec tho

 

When you mash gas pedal will it down shift in to lower gear ?

 

Yeah but not until after it's like done Choking on gas lol then it takes off
