WOW i can't believe how dirty my tb was. Bought some tb cleaner from Canadian tire sprayed her down and what a difference.

I couldn't beleive how dirty mine was either. It seems to run better now and have better throttle response. It still stutters or stumbles a bit when I quickly snap the throttle open though for some reason. It would be nice to get that one solved as well.
I notice a little stutter on my '00 GT if I mash the puddle down. It's like the entire engne cuts off for about a 1/4 second. I figure my tb has to be downright nasty.
Stupid question, but can anyone do a quick 1. 2. 3. writeup for me on how to do this?
Is it as simple as taking off the airbox, and tubing and the TB is right there then I just scrub her down?
Any info would be greatly appreciated.

Your best bet would be to disconnect everything from the throttlebody and remove it completelly before cleaning it. If you just take off the airbox and tubing, there is a screen over the opening of the throttlebody. If you have some basic knowledge of working on engines you should be able to manage it fairly easily.
got mine cleaned up. WOW what a diff. thx guys!
I just cleaned out my TB this past weekend. God it was basically completely black inside. I can't believe how ditry it was. I used Chemtool B-12 to clean it out. Jesus, I didnt even need a toothbrush to help with the cleaning, the inside of the tb was sparklingafter about 15 total seconds of spraying. I'm going to be using the crap for the rest of my life.
Cleaning the throttle body on my son's 2004 GP GT2 solved his start/stall problem also. Thanks for the help from this forum! Prior to cleaning, using my Autoenginuity ODBII scan tool I could see that the throttle plate was open 7 percent at idle. After cleaning it was at 1 percent. My conclusion is that the plate could not close completely due to the carbon build up. Also, while cleaning, I noticed that with the engine off, that the throttle plate rests at about 15 percent open, apparently with springs or something inside the throttle plate motor (not sure how it's done). If I moved the throttle plate closed with my finger, it would "stick' closed and not return to it's rest postion of about 15 percent. After cleaning, the sticking closed did not happen. I'd guess that during the start process the throttle motor closes the throttle plate and it sticks, inhibiting the throttle motor from opening the throttle plate at the rate needed to get the AFR mixture (i.e. air past throttle plate) correct for startup and idle. Even if my speculation here is wrong, I am sure that cleaning the plate fixed this problem. Thanks for the information on this forum folks!
I know what you mean:

I was able to get it this clean prior to returning it to ZZP for a core (didn't want my core charge to get dinged for being too dirty):

That was with careful use of carb cleaner. I didn't try too hard since it's just a core, but I felt it could've been better. What Chemtool B-12 did you use? Air Intake Cleaner?
