Here is a trick I use when replacing screws, this is from my 30+ years as a two-way radio technician. Insert the screw and depending upon the location with or without a screw driver rotate the screw 'counter-clockwise' until you either feel or hear a light click or pop sound. This click or pop indicates that the threads of the screw have dropped down inline with the threads of the anchor at this time you can now turn the screw 'clockwise' without fear of cross threading or stripping the threads. I hope you and others find this useful.

I've watched 5 videos (including yours) the past 2 days on how to do this becuae I am going to clean mine on my 2006 Dodge Grand Caravan...yours is the best! Thank you!

Your video was a tremendous help to me today. I watched it and completed step by step on my 2003 Caravan. It fixed my problem 100%. Thank you for great instructions from start to finish. God bless!

Hey Mc Fix It Excellent video! Another contributing factor to rough idle is at 19:40. Notice the vacuum elbow hose that attaches to the port on the throttle assy. as it has a crack in it thus an 'air leak' that will either cause rough idle or 'idle speed' not reducing properly at this time would be an excellent time to replace that item. Keep up the good work.

My dude! Another outstanding video. Thanks for listing all of the tools. I appreciate it! Keep it up!

Never use a metal object to hold open the butterfly damage can accrue use the plastics end of screwdriver or your hand and never reuse any gasket you are asking for trouble and inexpensive to replace! Use a child's toothbrush to clean instead of qtip does a much better job. Clean inside of intake if it is dirty as well.

Thank you for walking us through the how to video on removing the throttle body and idle air control valve then cleaning it and then putting everything back together. Great job!

Awesome video! I guess I have a project to do next weekend! Love the detail and tool list as well!

Great vid 👍 I appreciate the details!

I think this is my problem. I thought I'd need so many more tools to complete this job. I hope to this tomorrow or on the Holiday on Monday. Thank you!

Thank you for the full tool list. I think i can now do this project myself after watching your video. Thank you again!

You are the man. I did this with my van and it completely solved the idling problem. Thank you so much!

Q-tips are such a smart way to clean this. I've only ever used towels. I'm going to keep some of those handy in the garage for future projects!

Thank you very much for this video!! Your intake valve wasn’t near as dirty as mine was. I have a 2005 Chrysler Town and Country and I don’t think its ever been cleaned. My gauges were going crazy, every light on the dash was on, it was rough idling, and it got to the point it didn’t want to start. All the ground wires were checked and cleaned for corrosion and tightened down. I changed the alternator because It tested bad. I cleaned the battery posts and put battery post protectant on them. I changed the air filter too. The problems remained. I tried cleaning the IPM Fuse/Relay box because the connectors had corrosion on them. When I flipped the box over, 3 connector pins fell out. I had to order a new one from the Chrysler dealer. It was 20 days out. I changed the spark plugs and spark plug wires. I don’t think they put never seize on the threads of the spark plugs or lubricant on the boot covers. I put them on the new ones. After I get the air intake cleaned, I am doing an oil change and then it will be done. New subscriber here!! 🥰❤️

Very nicely done. Only note is that it would have been good to hear the idle before the fix as well as after the fix.

Fantastic video. Thank you for recording it

Great video. Thanks for putting this together. I have been having issues with a rough idle start especially after starting it up. There are times it sounds like it's going to stop my engine

Way to make it clean and solve your problem. Im hoping this is all it is on my town and country!

Can you take off the air intake assembly to give you more room?

i know it's been two years but when you put it all back together at 20:10 you can see your bottom small air hose is cracked up. great video

This helped me to solve the rough and unstable idle on my Grand Caravan, thanks a lot for sharing this video!

Great complete video with instructions and tools Keep them coming!

My 2004 doesn’t really go past 20MPH so it’s VERY ROUGH. To get up to that speed I’m lucky, I was told it’s the coil pack. I have a free scanner which I’ll take it to Autozone to get it scanned properly. Free scanner says P1693 P0301 P0123 P0015 (93) Where should I start? I’m doing the labor, shops charge so much. Thanks for the video !

Great video. Well put together! I appreciate all you are putting out on KZfaq. Keep it up!

Cleaned mine been 100000 made slightly better still shake a bit ,,,,,290000 miles it helped

Thanks for sharing. My throttle body was way dirtier than yours. Thanks for showing me how to clean it.

What’s the difference from “shop” towels vs regular paper towels?

Also use spray cleaner on the MAF sensor's electrode in the rubber air snorkel hose. Dodge calls this one a mass/air temperature sensor

Great detail and explanation. Thanks for sharing! The auto manuals can’t show everything once you get into it.

This might be my problem. Once the snow melts, I'm going to work on this

Just did this now, tested drive and it impove by a lot, but I can still feel roughness. And if the AC is on full power, the engine struggles and sometimes it dies. I'm not sure I'm gonna make my long drive tomorrow

Can you use something like a toothbrush or soft bristled brush?

I'll be doing this on my Cavavan soon.

don't forget to clean TPS as well with maf sensor cleaner, and clean contacts for all those wires, inspect/clean/replace air filter, spray MAP sensor with maf sensor cleaner as well, and inspect/replace PCV valve in the back (it all kind of works together and while there might as well inspect it all).

Do you need to change out the gasket on this after cleaning it? I’ve heard that it’s a good thing to do but wasn’t sure if it’s needed

Remove the 2 grub screws from the butterfly valve to give you greater access to the 'venturi' that return spring is really very strong...

Excellent video on idle fix and idle air circuit.

Awesome video! This is just what I need to do!

The problem I had with the van was a fouled sparkplug. Replaced all good now.

Fantastic, thank you!

Is that CRC Mass Air Flow Sensor Cleaner? It has something over the name and want to make sure to get the correct stuff to complete this project!

I have a 1981 dodge b250, 360 5.9 with extreme high idle and extreme squealing

Thank you.

This is a part best cleaned by an ultrasonic cleaner..Check them out....

Excellent video. I have a question maybe you can help me with. I have a 1996 Dodge grand Caravan. The throttle body has been cleaned and the idle air control valve has been replaced. The check engine light still comes on and the code that it displays says to check the idle air control system. Could other sensors be bad such as the sensor in the air supply hose or the throttle body sensor? Thanks for any insight that anyone can give me. The engine idles fine with easy starting and smooth acceleration. Unfortunately I'm in California and have to get a smog check for my registration. It will fail if the engine light continues to come on.

No.never change that change map sensor and maf sensor then clean that. Ive nevrer changed thia just clean

any videos on how to tighten throttle cables on a 2005 dodge grand caravan 3.3?

Good job 👍

that split hose causing a evap leak?

Was there loss of acceleration while a/c is on?

Could you use wd40 as a cleaner? Or would it be a bad idea?

I'm contemplating cleaning mine. But yours didn't really look dirty enough to actually block air flow. So I'm not sure if that's really what's causing my random idle issues.

Just saw your video an old tooth brush can do wonders to scrap the carbon.

After I cleaned the throttle body and put everything back together when I stated her up I got a check engine light and the idle was rough what could this mean?

Can I use carburetor cleaner?

any ideas or videos on the ECU?

It's still a little dirty . I just did my throttle body. Perfectly clean

I cannot find anything on how to fix the throttle wire it they r really loose and not happy bout it

Why does this get so dirty?

Do you have to do a idle re learn after this

A small toothbrush might help for cleaning.

I had no rough idle until I replaced injectors. And got p1193 iat sensor issue. Would the tb or iac being dirty now show fault now that injectors are working now?

my car idle really rough I scan it and it says map sensor , I changed it and still the same.

Bro... my back side was all black and caked up.

Pro tip... buy $1 store electric tooth brush.

I tried cleaning this, but it did not help. The van still runs rough.

👍🏼👍🏼🌸👍🏼👍🏼

Did all that, did not fix the problem.

This isn't for a town n country.

excellent video
