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

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.

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

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.

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

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

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

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

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

Hahahaha I died when he started reading off the plug sizes

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.

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..

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

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.

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.

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.

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.

Thank for sharing that's very helpful to me!

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.

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

Hey did you make a part 3. ???

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

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

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.

556 & 308 plugs. Where can I get them?

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.

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

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

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

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

Motor mounts??

Should only use Throttle body, or Carb cleaner.

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

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