i find it kinda cool but annoying at the same time. after i replaced my seals on my TB in my 95 gs-t, I put everything back on (damn those 2 rubber coolant hoses that nobody mentions in they're faq's they're just a pain in the ass) well I probably put the tps back on at the wrong angle or maybe even the wrong way? duno? but between shifts my car will rev up about 500rpm but once the car is warmed up it doesnt do that. plus for some reason now no matter how I set the screw for my idle, it seems to idle at what it wants from when its cold to when its hot. like under 500rpm at idle instead of 750 where it should be. anybody have they're 2 cents to input to help me out? thanks!
 
PLUS I just sprayed a 3rd dose of some GUNK tb cleaner into my tb while my car was running (like instructions says) till it died at least and then sprayed summore and started it up, and repeated a few times. well now I noticed when I barely press the gas, it will rev to 1,000 and if i hold the gas there it will go up to 1,500 and back down to 1,000 then back up and back down but if i press it just a bit more it will rev up to like 3,000 and stay there steady. im guessing its cause my tps sensor is off by a little bit and i dont have the tools to change it right now to find out, since im almost 2 hours from home in myrtle beach, sc.
 
Actually, I don't think you are supposed to put throttle body cleaner, or any other cleaner, into our throttle bodies. If the cleaner gets into the idle air bypass holes, it can screw up your idle air control -- which kinda sounds like the symptoms you are seeing. You are supposed to block those holes if you are going to use a cleaner on the interior of the throttle body.

Go into your engine bay and open the throttle body butterfly manually. My money says it's sticking open and closing slowly.

before i put it back on the car i manually tested it jerked it open and closed harshly and even softly to see if it would stick. but it only stuck just a very little when it was closed for a second but it quit doing it after about like 50 times of me doing it and me drenching it in GUNK tb cleaner. is there only one way to put on that butterfly? it kinda seemed like I could put it on the wrong way and it still seem like its on right. (yet even tho i marked it on the tb and the plate like u should.
