How To Clean Your Throttle Body and IAC (Jeep Cherokee XJ)

[@cdaudert]

Excellent video! After watching and replacing my IAC, my XJ is running great again!

[@KCars]

Awesome, thanks for watching!

[@nathanmccumber8965]

​@@KCarsyou got video for a/c. I recharge my a/c still blowing hot air I don't have leak.

[@KCars]

@@nathanmccumber8965 unfortunately no. I actually don’t even use my AC

[@LanceDean]

Thanks so much for this video! My XJ runs and idles like new again! I've had rough idling and stalling problems for months and this made all the difference.

[@KCars]

Glad I could help, thanks for watching!

[@tanner6538]

You make pretty great videos. Nothing flashy, but no lack of info either. A-grade.

[@KCars]

Thank you!

[@Electroskill]

Hey man, thanks for this video. My 01 XJ went from running OK to completely stalling out at idle within a matter of a couple of days. About $75 later and she's running like new.

[@KCars]

Glad I could help, thanks for watching!

[@Screamingz1]

What’d you do to fix it? Buy a new iac?

[@Electroskill]

@@Screamingz1 I took the throttle body off and scrubbed it clean with carburetor - parts cleaner. I just purchased a new IAC from AutoZone, since my original IAC had never been cleaned and I wanted to start fresh. I now know this is basically a maintenance item to clean out periodically.

[@Screamingz1]

@@Electroskill nice man. I’m going to clean mine soon. It like to die after real light throttle sometimes. And idle funny. The iac may be playing a role in that. Hoping so at least.

[@Electroskill]

@@Screamingz1 Sounds like that's likely the first thing to check. I can tell you this. I had noticed that my Jeep seemed to be idling a little rough with low RPM, but didn't have any problems otherwise. Then one day, I drove two miles away to my gym and it stalled while I was parking it. On the way home, I had to keep my foot on the gas to keep it from stalling. By the time I got home, it wouldn't stay on at all in idle. That's how fast the problem progressed. The entire throttle bottle was caked. I probably could have gotten by with the existing IAC after I cleaned everything, but since the sensor was already 21 years old and pretty cheap I just decided to replace it while I was in there. Good luck!

[@dagdernit572]

My 98 Jeep TJ was idling a bit rough and thoroughly cleaning it fixed it and seems to be a lot faster too, lol. Your video helped me alot!!! Thank you 👍

[@KCars]

Glad I could help, thanks for watching!

[@chazdesimone7306]

Excellent instructions, concise with good explanations. I like the colorful wall in the garage too!

[@KCars]

Glad it was helpful, thanks for watching!

[@paulsfrs3466]

Thanks for this, I’m gonna do this tomorrow when I have time. I almost ended up buying a new ECU 😂

[@KCars]

Awesome, and how did that happen?

[@ari1234.]

My problem is in cold start has high and fluctuating idĺe If I tap on the gas pedal before starting then the idle is normal..going crazy

[@Lou4130]

This will be helpful as i was planning to do this to my XJ very soon! I have a little rough idling when i start it up but after its warm its better/ok. Also did you ever do the waterpump/thermostat video? I gotta do that as well.

[@KCars]

Glad I could help, thanks for watching! I actually had a shop install the cooling parts, here’s that video of you wanna check it out: kzbin.info/www/bejne/b4fGo5mHdrWDg9Usi=GksAx0rBbUjO5OEc

[@njrepresent200]

I pulled mine off to clean it,because my engine stalls at idle sometimes and realized the O-ring on my IAC is missing. Is it neccesary to have that O-ring? all the auto stores near me say they dont have the right size for it

[@KCars]

I’m not sure if it’s absolutely necessary but I would definitely try to get one on there

[@njrepresent200]

@@KCars thanks man! Couldn't find one that fits perfectly so through a smaller universal one that stretched a tad bit. The stalling turned out to be from the coilpack anyways so I'm not too worried

[@KCars]

Good to hear

[@72cut13]

Excellent. Please do more vids on jeep cherokee/comanche

[@Ezell6]

Love this video! Explained everything very well down to simply how to take out a sensor. If you have more xj videos you basically got a view and like from me already.👍

[@KCars]

Glad I could help! Thanks for watching! I have a bunch more XJ videos if you’re interested: kzbin.info/aero/PLCIz0TOjZIkV8MYDzYgP0ZpaBzw_eaCio

[@xxjoseneilxx]

Thanks for the video, I'll do it. Tomorrow I have a big question, it could be excessive fuel consumption.

[@KCars]

Thanks for watching!

[@djBeni93]

What brand besides mopar do you recommend for the IAC sensor on a Jeep Cherokee 1998? Great videos, man. Thank you.

[@KCars]

Personally I would prioritize mopar since that’s what they were made to work the best with. Other than that you could look into crown automotive as an alternative. Thanks for watching!

[@philromeo9481]

Is there a certain way the gasket goes on I cleaned my throttle body Jeep ran good before that cleaned the iac put the new gasket on and now runs ruff and shuts off u think maybe the gasket idles at like 200 rpm

[@KCars]

I don’t believe so. Something may have gone wrong with the IAC possibly?

[@TheNinjaNarwhals]

How quick are you in replying? I just swopped out my tps and cleaned my throttle body but now it’s idling at 2500-3000 idk what to do

[@TheNinjaNarwhals]

There was no gasket and I didjt buy one. Could that be the issue

[@KCars]

Looks like it took me two hours to reply. Did you install it back in the same way? And if there was no gasket before and it was working fine before then I’d say that’s not the issue

[@TheNinjaNarwhals]

@@KCars it wasn’t “fine” per say but it definitely wasn’t running like this. One of my buddies said to disconnect the bat for a few minutes then connect it back up and let it run for a few minutes as well to see if the computer resets the idle since it was dirty and now it’s clean? Idk. And yeah I put it all back together the same way, I just hope I didn’t fuck anything up taking it off

[@KCars]

@@TheNinjaNarwhals hmm ya you could try that. I don’t think you could’ve messed anything up especially if you put in a brand new sensor

[@TheNinjaNarwhals]

@@KCars I cleaned it with throttle cleaner but I couldn’t get the iac off cause I didn’t have the correct bit for it so that didn’t get a proper clean as well

[@Z0S084]

Great video. I always have a rough idle on a cold start up. But it goes away after I drive around and warm the engine. I can turn it off, start it back up and it idles fine as long as it's warm. What do you think that could be?

[@KCars]

Have you tried replacing the sensors? Specifically the IAC or TPS

[@Z0S084]

@@KCars no, I plan on doing that first and cleaning the throttle body like you did. If it were the upstream CO2 sensors the check engine light would be on right?

[@KCars]

I would assume so

[@jamesthehandyman]

Can you clean the maf sensor with the regular throttle body cleaner

[@KCars]

Ya I don’t think that would hurt. I used it on the IAC

[@donphillips7705]

Wish to know what light u have on that jeep nice lights and how the look when off road or on dry pavement

[@KCars]

They are Quake LED headlights. Definitely a huge upgrade from stock

[@officialWWM]

Why do we need to do this? Was the Jeep running badly?

[@KCars]

Not it wasn’t. I just wanted to clean it up to not cause any issues down the road

[@officialWWM]

@@KCars oh, ok. Good idea!

[@jsemaj8451]

Where did you get the fog lights? Great video, thanks

[@KCars]

Those are the stock fog lights. Thanks!

[@BUKWulfSh0t]

Is the throttle body gasket important?

[@KCars]

Not sure how important but I’m sure it’s good to have one

[@eagleturtlestar]

Love this video and cleaning it . Good joooob!

[@KCars]

Thanks!

[@ultrapac2568]

Completely off topic. Charger, Challeger, or camaro as a daily driver ?

[@KCars]

I’d say charger. If you don’t have a need for 4 doors and more back seat space then challenger. I think the Camaro might be too small for a daily

[@rodrigomendoza8428]

I have a charger as my daily

[@rodrigomendoza8428]

So my jeep has sat for 3 years, i added 8 gallons of prem gas to her thinking that would help, however she died after driving 80 miles... i think i ran outta gas... get her to the side of the road, crank crank crank nothing... crank crank crank, she tries to start, dies. Got her running after adding 5 gallons of gas, however, when i give it gas she dies, let her idle for a bit, idles rough ( died sometimes). Now she wont start again, maybe i need to add like 10 gallons of gas with some cleaner? sounding like she's putting herself out... not sure, either clogged or not enough fuel. maybe u have an idea? im gonna test the fuel pressure today and see what she is at, i need 49, if she's good, gonna order all the sensors and change them out, clean the throttle body, add fuel and add techron concentrate to the tank

[@KCars]

That sounds like a good plan. I was going to suggest replacing the sensors but seems like you are already planning to do that. Good luck and let us know if that ends up working for you

[@wjb111]

New sub!
