Jeep XJ - Rough Idle & Stalling Issues? Clean the Throttle Body & Test the TPS Sensor 

He is so cute, great to see father and son fixing the jeep🙏

Not only was this video incredibly informative while I chase down my rough idle and cylinder 3 & 4 misfire due to heat soak, watching your interactions with your son made my night. Great stuff, I look forward to more informative XJ repairs from you and your son!

Kid knows his stuff

If you have a friend with a lathe, i suggest doing an intake manifold match to the throttle body. The bottom of the TB is about 55mm give or take, and the IM is roughly 61.5 to 62.25mm. I bored mine to just below the butterfly on the short side and the idle is significantly smoother, and a snappier throttle response. Happy new years to you both!

What a handsome little man Preston!! Great cleaning too!!

Good, concise, informative, and nicely edited. I love the overlays you put on there, because as a beginner, I have no idea what I am looking at when looking at my XJ's engine bay LOL. Learned something new. My XJ has been having a rough start to the point where I had to pump the accelerator for it to even start. But today, it started, stalled, then never was able to start back up. Starter still turns over though. Looks like I am gonna be cleaning the Throttle Body of my '98 XJ.

If ur still having issues i just did my fuel injectors and IAT the IAT is very important as well most people over look that part

Happy New Year Preston! Looking forward to a great 2023 with you fellows. I experienced the same thing with my 88 back in the summer and it was crazy how dirty the IAC was. I like your Jeep hat Preston. Be sure to keep your dad in line. Thanks for the video!

Right on, thanks. Using mom's toothbrush was the key ;)

you both are amazing, love the videos, great work!

Another fine job by the father son team and another great suggestion by Paton!

Thanks going to replace IAC tomorrow in WJ 4L

Going to do this tomorrow. My jeep is stalling, rough idling and I swapped out the TPS SENSOR and it was running fine for a few days, up until today. Bought a new IAC sensor, replaced it and it is still doing the same thing. Wanting to stall and high RPMs. Cleaned what I could since it got dark and I have to be up at 4AM for work lol but thank you for this.

You gained a new subscriber. I’ve only seen a few of your vids. I like how you keep Preston involved with being able to see what you are doing through the camera and phone. He has caught you making mistakes. 😊 He has a eagle eye and actually comes up with good suggestions and questions. That’s great that you spend that kind of quality time with him and you have the patience of a saint. If you don’t mind my asking, what kind of condition does he have? I have a ‘93 Jeep Cherokee Sport 2dr so I like the play by play I fo you put out. Keep up the good work and awesome family time.

super cute, getting the job done with your son.

I have the same jeep. Same color and everything. My dad left it for me when he passed away. He replaced alot of stuff in it. I've replaced alot of stuff in it. It's always something new but I don't mind. I just did some rust repair on it and painted the rockers. She looks nice. Get along of complements. Wasn't sure about that gold color a d matching gold wheels when he first bought it but it's really grown on me and I've put some nice bfgs all terrains on, painted rockers and fender flares and black trim. Dad would be so excited to see now. Replaced alot of things mechanical. Most on my own. That's the cool part of these xjs. They're almost easy to work on lol. Took me five minutes to put new head lights in. My 96 f150 took me like 7 hours lol. Love the simplicity and nimbleness of the xj. Plus I get a stupid amount of compliments on it it's ridiculous. I'm really getting to be a huge fan of the xj. I see exactly why dad owned 4 of them. They're the greatest suv ever imo

Really enjoyed your video your lucky to have a great helper 😀👍

great team

You guys are good mechanics. Nice job 👍👍

Good job. Glad Link and Preston was there to guard your boots and to help you. Did you recheck the TPS after you attempted to remove it? From my experience on my MJ 4.0, it doesn't take much to get it out of adjustment.

Dude sounds like Pauly Shore

how did you repair the wire after stabbing it

You guys rock thanks for the great video

Great video thanks for the tips!!

Oh by cleaning your carburetor would it help the RPM?

Hi I’m having some random stalling on my Jeep , when I’m at stops it idles low once I press on it’s a rough acceleration any ideas on problem?

Can Anyone help! My 01 Jeep Cherokee just stopped running before pulling out of drive-thru. No engine light or overheating gauges came on. After waiting 30 mins...started again with no engie lights coming on. Your comments please.

Good video

My 2002 Kia Sportage was the same thing, IAC, but I also had a cracked exhaust manifold. Now it runs better. Also your e-mail address in the about section doesn't work. Do you have a different one? God Bless

What color xj is that?

Rumanian plate on the wall, RO.😅

Wow my jeep is not a rock crawler and it only gets 12 miles per gallon!! It’s not lifted! It only has regular tires!!
