best way to clean out throttle body?

so whats the best way to clean out the throttle body? spray some carb cleaner in it or what? i am having rough idle issues and i pulled out my IAC motor the other day and the cone was covered in black gunk so i am assuming it is pretty dirty in there. i am about to replace the TPS because i heard that could be the problem but if i could save myself $40 by just cleaning the throttle body then im going to try.

Remove the throttle body and meticulously clean it on a bench. You don't want all of the gunk and crap to get into your motor which will happen if you clean it while it is still installed.

i would say spray it down real good and wipe it off making sure theres no water left over. and then take a metal scrub/ rust away to get a nice polished look and it will help get rid of any starting rust

Aluminium throttle bodies don't rust

You should be able to effectively clean the old TPS and the bore it goes into.

I just cleaned mine with seafoam. It worked great, taking off the throttle body is easy only 4 bolts and 2 elect. connections and the throttle cables. I then took off the air flow senser and cleaned them both seperate. reassembled then put it back on. It took less than 45 mins.

What about the sea foam spray when you spray it in the throttle body while the vehicle is running?

It will help, but it won't do nearly as good a job as taking it off and cleaning it, and as a previous poster said, that junk's gotta go somewhere and when you use Seafoam with the enging running it goes into your engine. Removing and reinstalling the throttle body is no big deal and the gasket is relatively cheap.

Oh, and before you ask, the linkage to the throttle just pops off - there are no nuts or anything holding it on...

could someone please take a picture of their engine bay and circle what i need to remove to take the throttle body off? i have a 95 2.5L and i see a lot more attached to the throttle body intake than just the manifold bolts and some sensors....

Loosen and take off the massive hose from the filter box. Take it completely off both ends so its out of the way and put it somewhere clean and safe.

Disconnect the TPS and IAC Valve connections.

Remove the throttle cable, its easy, just pop it off. And unhook the spring from the mount leaving it attached to the TB.

Loosen the 4 bolts holding the throttle body and remove them and the throttle body will come loose. If its stuck on give it a LIGHT tap with a rubber mallet, or a normal hammer.

Clean the old gasket off both of the mating surfaces and try and keep bits out of the intake manifold.

Then get cleaning!!

Install is the reverse of removal.
A lot of stuff looks like it goes to the TB but its plugged into the Intake mani. instead.

Hope that helps.

If u do clean the TPS do not spray it with carb cleaner. It is too stong and will damage the sensor. Use tps sensor cleaner.
