I hear mixed opinions on this, some say do it, some not. The Toyota dealer says they use a brush moistened with some TB cleaner or seafoam and a shoprag. Brush it on good and leave it 10 min. Repeat if necessary. They told me not to flood it with cleaner because it could get in the electronics, just a small spray. They said you can't damage the TB if you gently push it open manually, just disconnect the connector and make sure the car is off. According to them it makes a difference. I do it with no problem on the older cars but the electronic TB worries me.

Is this something they suggest you do and that they'd do for you?

On my Hyundai Gen Coupe I have pushed the throttle body open when the key was on with no problems.

Id probably follow the dealers advice. I clean my TB with a heavy spray but its not electronic.

Do this on Acuras all the time. Have to go in and reset the throttle adaptations after though or else the idle gets wonky.

Even if you get the TB wet it is going to evaporate and dry out quickly within 5 minutes or so.Might be a lot of smoke when you first start it up if you happen to spray a lot of cleaner beyond the butterfly, but that really wont hurt anything. Just wipe it out with a shop rag. Hard to go wrong, Just do not use throttle body cleaner on the MAF sensor. Best just to buy the CRC pack with a can of TB cleaner and a can of MAF sensor cleaner. It will last several cleanings. I clean the TB and MAF sensors about every 1-2 years and the CRC 2 can pack cost about $5-$7 max at most any part or hardware store. Of course some people like "deep creep" which also works for TB cleaning.

I've cleaned the TB on my Rav4 and Corolla. Used a rag and some spray. Think it was CRC throttle body cleaner spray. Used a screwdriver to drop the flap open.

They wanted $550 for the spark plugs and $150 for the TB. The spark plugs are very expensive, but I found that Denso has two identical plugs with different part numbers and they can be had for much less. They use the TT iridium plugs, I have them in my Explorer, great plugs!

That's what I thought. The Spark plugs aren't fifty dollars and a can of Seafoam at Walmart is $6 and change!

I removed it on my Tundra to clean it, as I was having an idle issue. CRC cleaner of some sort, from Walmart. Haven't done on any other vehicle; I'm not sure I'd bother unless if it was easy to do, or more likely, I actually was having an issue.

What vehicle and engine are we talking about here? $550 for plugs on a Toyota?

The Lexus with the 2GR-FSE 3.5L engine. The plugs are $40 each and about $250 or so labor, tax.

When I cleaned up a Toyota ETC throttle, I was able to move the plate and wipe it clean. No CEL or idle wonkiness, I think the car checks the throttle "zero" point when the PCM boots up.

I've cleaned the electronic (drive by wire) throttle plate on my scion tC. What I do is clean the one side with swab moistened with throttle body cleaner. Then when I'm done with the "outside" side of the plate, I have someone turn the key to ON, but not start the car, have them press and hold the gas pedal so the plate will open up.. and I clean the other side.. Then have them release the pedal and turn the ignition off.

I have heard about messing with the "HOME" position of the plate, and usually the Toyota's will re-learn where that position is. But hey, I'm not going to force a high torque electric motor by hand. One of these throttle bodies cost around $600-700! ouch..


Another thing to think about.. DO NOT SPRAY THROTTLE BODY CLEANER DOWN THE THROAT!! On Toyota's the intake manifold on some engines is a nylon/plastic!! That means the cleaner contains acetone, you'll MELT your intake manifold! Best do you use a rag with the cleaner on it, or a cleaning swab with it on there.

another thing.. $40 for a spark plug? Highest I've seen was an NGK for a nissan at $18-20 a plug.

Have someone press the gas pedal down while you clean.
