Dissembled and cleaned throttle body. Pics

[Freebeer187]

So, today I had an itch to work on the Grand Prix. I always wanted to clean the throttle body, but I could never get that damn screen off (without mangling it up). I used to spray a little maf safe throttle body cleaner from time to time, but I wanted to make sure it was really clean. I recently met up with James (Turbocharged400sbc) and he explained to me exactly how to perform this job. Following his steps I was able to knock it out.

I picked up the gasket and today I began working on it. It was actually very easy to perform. The hardest part was getting the barrel throttle cable off (it was very very easy once I figured it out). After that everything went smooth. As you can see it was very dirty. I tried my best to clean everything and ensure every trace of gasket/debris was removed. Some areas simply were caked on and were permanent.

Here is a small video of meaning driving it around the block. I gave it about 75% throttle. Not very fast, but I notice a small difference. Now I just need to get a MAF

Delete that egr.

I'm thinking about putting mine back on.

Whats the benefit of deleting the EGR?

 

[Bob Kazamakis]

I got one you could have.

 

[Bob Kazamakis]

The benefit is not having that giant thing in your engine bay.


It's not really a benefit unless you go IC. It'll keep everything a bit cleaner in there though but you'll get a tiny bit worse mpg

 

[DanJ]

I just need the hose. When headers come off, the EGR is going back in.

I see finger prints. That will hurt you.

Nice though. When I switched to the N*, removing and replacing was super easy. No paper gaskets to worry about either.

 

[Freebeer187]

Hehe i have no idea where the fingerprints came from. They are pretty much burned in the metal so to speak. I couldnt get them off!

To get the screen out...remove the large C-clip...then remove the maf. Then sick your index finger in the maf hole and tap the screen out.

Is it ok/recomended to run the car without the screen?

if u ask ClubGP it adds 10 hp.

No, if you need more flow, go to a bigger outboard maf. The screen is there to smooth flow over the maf wire. Removing the screen does increase flow, but it affects idle and WOT.

People will tell you that they didn't notice a difference, it DOES make a difference...it's generally a bad idea. I was even a proponent of it until several years of experience proved me wrong.

i ran no screen in my 1st gtp for a week and the car ran like durty donkey balls. slapped it back in, ran great.

glad it worked, now get a maf and better intake

snap ring pliers are kinda necessary for that maf screen...

I use a thin screwdriver and spiral it out.

...or pick, like ron im lazy and prefer not to walk over to the toolbox if my pick of destiny is handy

 

[MikeyLikesIt]

Nice, what did you use to clean it? Just some cleaner?

 

[DanJ]

I used 2 small nails held in vice grips before I got snap ring pliers. Ghetto tool creations.

Yup, same goes with the FPR

My Dad comes by, and is always like "oh, you need this tool..." when I am out in the garge working. He'll poke through the garage looking for it, and by that time I'm done.
