How To Clean a Throttle Body - Toyota Matrix / Pontiac Vibe Rough Idle - part 2 Tune Up

In this video I remove and clean the throttle body on the 2007 Toyota Matrix. I am attempting to fix rough idle and everything I've done has helped but vibration still persists. Stay tuned I have one more idea of what could be causing this.

[@mrc2165]

FYI...clean your MAF sensor while your at it, but use MAF spray cleaner.

[@mikebeckworth2965]

Just cleaned my throttle body and it made a great difference. When I restarted the car, the RPMs went up to 2000 and I could get it to come down. I shortcut the procedure and didn't unhook the battery cable. I realized that the high RPMs was a learned position to the ECM. I unhooked and then reconnect the cable and the idle was then normal. Running great! Thanks.

Witch cable

[@sidgysoho1960]

Wow, you did all of that and only completed half the job. The 1.8 liter ZZFE Toyota engine is " notorious " for compressing the intake manifold to head gasket. It's intended that way to check the thermal expansion properties of 2 dissimilar materials. At the correct interval ( heat cycles ) replace the $9 gasket. With 1 from Felpro.

Thank you for posting! Really helped me out with my 2005 vibe

The Intake Manifold Gasket, Part #22271-21060 costs $13.85 at Dolan Toyota here in Reno & they are out of stock & will have to order it.

[@MrBobsVids]

Super smooth, nice narration, very helpful, thank you!

[@acegolfman3203]

My vibes throttle body needs to be cleaned every year as the gas peddle gets sticky. The cleaner doesn’t work, I have to take my hand drill with a rounded soft grinder bit from harbor freight and lightly grind around the butterfly contact. Works great every time, 9 years now

[@acegolfman3203]

I never remove the throttle body, seems too complicated with potential to mess up

[@58gennaro]

very helpful. Think I'll heat the garage and tackle it today.

[@STREETFIGHTER50]

Thanks for the video! I will do this on our higher mileage Vibes

[@howbout-it3520]

Hahahaha I died when he started reading off the plug sizes

[@igorbogordetski2319]

Your target is just to dissolve blackish built up with air intake (brake) cleaner and remove it from inside of "Throttle Body". Use normal toothbrush! No brass ! And to achieve good result no need to remove that "Throttle Body" unit - just remove rubber intake pipe and clean the unit inside manually opening the damper. Do not go too deep - just before and beyond the damper. Use soft clean cloth to wipe the dirt.

[@acegolfman3203]

Yeah, i never remove it. I use an electric drill with a soft grind bit to clean it as the fluid and toothbrush never work. So no fear of being too aggressive imo

[@AmeriFanPicker]

I think a bigger danger than operating the butterfly, is cleaning fluid getting into the idle speed control valve (the electric motor portion). .

[@donovang6911]

I get a rough idle AFTER the engine warms up in humid conditions (fall, spring and big temp fluctuations in winter). I'm going to try this procedure and see if it helps. I already change out the plugs and cleaned the MAF sensor. The throttle bounces up and down somewhat at idle and it's more pronounced while in gear.

[@TheHandsOnChannel]

Good luck!

[@Fastarek]

Have same problem here did it help after cleaning the TB

[@TheHandsOnChannel]

@@Fastarek It did help but it didn't solve the problem. The motor mounts was the cause of the problem.

[@eliseomartinez3258]

my 04 corolla has a vibration at idle too, i check my transmission mount and its cracked, saw a video about hope this helps replacing trans mount and it fixed the cabin vibration, now i need to replace mine too.. hope this helps you too. good luck..

[@niceguy192]

i did this tune up this weekend past and i swear mine looked just a dirty, +200k on the dash by the way. I also went ahead and cleaned the MAF sensor, mein that thing was visibly coated with dirt. Those 2 things i did and already see a change in response when i press the gas. Next project will be the plugs and PCV.

[@pampierce]

What is a MAF sensor? What is a PCV?

[@niceguy192]

@@pampierce itt easy to locate on these engines, the MAF is right after the air filter box, small square/ rectangular shape with 2 screws holding it down on the top with a 5 pin connector. The PCV is also easy to stop, its right at the back of engine screwed into the valve pan cover, you would have to take off the engine cover first to see it good.

[@dabcorn]

Was hoping to see how that electrical connector release worked. The one on the backside of the throttle body.... anyway, thanks. Your videos are nice. Got an '05 & 06.

[@TheHandsOnChannel]

Thanks for commenting. Sorry I couldn't get that plug connector. Seems like it is a squeeze to release plug. Good luck.

[@CambodiaWonder]

Thank for sharing that's very helpful to me!

[@TheHandsOnChannel]

You are so welcome!

[@teymur85]

I’m having the same rough idle issue. Is there a part 3? The first two parts are very helpful- thank you for the videos.

[@TheHandsOnChannel]

I found the motor mounts were bad and causing the vibration. I did a video series on how to check/change the mounts.

[@dobe2050]

@@TheHandsOnChannel thanks for this info

[@clys69]

@@TheHandsOnChannel which mounts were the culprit?

[@andrefiset3569]

I dissasemble the unit and i can say the gears are nylon and sturdy and the little motor turns freely. It looks like an ordinary electric motor.

[@STREETFIGHTER50]

I’m gonna switch out my rubber plug set for my brass ones! 😂

[@TheShakir98]

damn i couldnt even get mine out, the bolts are so damn corroded that even a slight force would wear and brake the bolts

[@dobe2050]

heat them gently with a turbo torch

[@tyfixes5630]

Sounds like a breaker bar will be needed

[@SnwBrdFrvr]

Does coolant actually come out of those hoses when you take them off? Also is there a gasket or oring that should be replaced between the throttle body and the intake manifold? I'm going to do this, trace the intake gasket, and probably also replace the valve cover gaskets because I noticed my motor has oil residue on it above or around the intake manifold.

[@joshatkinson01]

I just bought my gf an 05 Vibe. It's hunting for an idle. It's not like a Honda with a bad IAC valve, but a slight hunt, do you know what this could be

[@TheHandsOnChannel]

It has an idle relearn for lack of a better term. Basically when you disconnect the battery for a few minutes and then restart the car it will self learn where to idle. IDK if this will help but it's free to try. If that doesn't fix it it could be an intake leak somewhere.

[@joshatkinson01]

Appreciate it sir,I'll give it a try. The gentleman that owned it before me just had a new exhaust manifold put on and he said they didn't replace the o2 sensor, I have 2 diff o2 codes (P0031 & P0134) this could possibly affect my hunting idle, I'm going to buy a new upstream Denso o2 sensor and see if it helps

[@slalomking]

Hey did you make a part 3. ???

[@AustinWilhite]

[@DaeguDown]

Brake cleaner on a MAF is not recommended. Could be too caustic since the MAF is a VERY sensitive piece of equipment.

[@DiverCTH]

Are those plugs .0556" or 5.56mm? Also is it OK to use the painted steel ones or should I stick with brass?

[@SnwBrdFrvr]

My 06 vibe with 40,000 miles on it idles rough while in drive at a stand still. I cleaned the maf sensor. I sprayed it down with carb cleaner to expose a evap leak but it didn't change the idle at all so I doubt it's an evap leak. I guess I'll try this. Any other ideas? I had a p0171 code which is fuel trim system lean. But after cleaning the maf and resetting it the code hasn't came back yet.

[@rog8201]

Replace the intake manifold gasket.

[@dborg56]

556 & 308 plugs. Where can I get them?

[@myriammarquez9716]

My husband tried on corolla 2005 still vibrations he thinks bad fuel injector is causing bad idle

[@TheHandsOnChannel]

This one turned out to be bad motor mounts. The lower rear mount was causing the bad vibrations.

[@myriammarquez9716]

I'll let him know 😀 but you can tell when sitting red light , the rpm goes down to 800 thats when the car starts rough idle. But if the car is 900+ rpm is smooth . Thank you god bless

[@dougkissick584]

Motor mounts??

[@michaeldiaz2439]

Should only use Throttle body, or Carb cleaner.

[@whitechris720]

I tried using the 556 plug with my custom 556 applicator. The damn thing bounced off the block and landed in my leg.

[@TheHandsOnChannel]

LOL!

[@igorbogordetski2319]

Toothbrush should be used !! even already used toothbrush :^) No brass or steel brush ! - you will scratch or damage the working surface ...

[@acegolfman3203]

No, I use a soft grinder bit on my hand drill and it works great!

[@curtis1951]

I've heard that the motor mounts are week on these and could cause a low rpm vibration.

[@TheHandsOnChannel]

That was the problem with this car. After I changed the mounts it was much smoother at idle.

[@curtis1951]

@@TheHandsOnChannel Did you use OEM Mounts or aftermarket? I changed my mounts with aftermarket mounts and now I think it vibrates worse.

[@TheHandsOnChannel]

@@curtis1951 I used aftermarket parts from ebay, sorry I cant remember the sellers name. I have heard other people complaining about some of the repro mounts. Saying they were loose and sloppy. You might try to tighten it up as much as you can and see if that helps. Mine were tight.
