throttle body cleaning

Can anybody tell me if it is ok to push open the throttle butterfly with a finger, to spray cleaner into the bore? I am working on an 04 pontiac
grand prix and I want to clean the air intake because it is pretty dirty. Is it best to unplug the wire harness?

Yup, using your finger is the best way IMO.

I unplug the harness...it only takes 5 seconds.

If you are supercharged you don't wanna use any cleaning solutions. They can destroy your rotor coating.

yeah, don't spray IN the intake... And remember to leave it propped open for a while to evaporate. An intake full of tb cleaner doesn't combust just right...

what would you use then because i'm wanting to do the same thing to my gtp

Do not fill your intake with throttlebody cleaner. Just scrub down the throttlebody plate with throttlebody cleaner and call it a day.

It only takes like 5 minutes to remove the tb from the car, 4 bolts.. and then you can go to town with a rag on both sides, then get a rag wet with tb cleaner and wipe down as far as you can reach into the intake.

This is the best way to clean a throttle body. I'd highly recommend it to anyone that has not cleaned their TB. Amazing what a difference it makes.

Thanks for the info, I think I will try my hand at taking it off. Probably get a much better clean and from what I read it should be simple.

While reading his thread I pulled, cleaned and , replaced TB . Freaking easy lol .

what about the pedal strings do they have to be re-adjusted?

nope, take them out, take tb off, put back on and clip them back into place.

I was gonna clean it since I hadn't in the 6 years that I've owned it. Then I saw this and said I'll check it again in 6 more years.

Woah.

EGR delete maybe?
