if you're not too careful and leave the tb installed you MAY have issues of fouling plugs. I fouled mine the last time I cleaned my tb....but i used an excessive amount of tb cleaner too...

that is good to know also, i think im going to remove it to clean it carefully.

You had excessive crap in there, not cleaner.

mine stuck and i cleaned it and didnt do anything i ended up just moving the throtle cable to have it open the just slightly to keep it from touching that stoper thats on the tb it was actualy sticking to that

ha if you remove your egr you will never have to clean it.

not true! I have an '02 that came from the factory without an egr and it still gets carbon all over it. I think you would have to remove the combustion to eliminate the carbon

Usually cleaning the throttle body will cure a sticking gas pedal on a cable driven vehicle, although I know for a fact that the 99's had a problem with the throttle bodies sticking and it wasn't due to carbon build up. I had the same problem when my truck had only a few thousand miles on it, and the throttle body was totally clean. I checked it out myself and the throttle body assembly was at fault. I brought it in to the dealer since it was under warranty at the time, and there was a TSB outlining the the exact problem and stating to replace the throttle body with an updated one as the fix. (the problem would usually happen on the highway after letting off the gas and allowing the throttle body to sorta slam shut...then when I went to accel, the gas pedal would stick)

how do you do the throttle body bypass.....

i know on the F-bodies you take the water hose on both sides and add a link to make it not go thru the throttle body.

Same thing on the trucks. alot of guys just take the hose from the rad and connect it directly to the port in the head, eliminating the short hose from the head to the throttle body. From what I hear, the hose off the rad is long enough.
