Default Help? Throttle Sticking?

First off, I have a Cammed 2002 Camaro SS 6 Speed.

Textralia Clutch was installed 2 months ago and since I don't drive my car that much, I just got done breaking it in. I changed the master out as well as the slave and all that other happy **** when I was in there.

The reason I installed the new clutch and Slave/Master is because I was at the track last year with the stocker and when I shifted at 6500 from 2nd to 3rd, the tach shot to 6800 (rev limit) It didn't hit the limiter but got right up to it. Put it in 4th and same story. Finally slammed it into fifth and the rpms came down. I was off the gas from the shift into 3rd.

I figured my clutch was fucked so I replaced it. It just did the exact same **** to me again today when I shifted at 6500 on the street.

I honestly didn't notice if the pedal stuck to the floor but I do know the gas pedal was not being touched. WHAT THE **** IS WRONG WITH MY CAR?

I've run through everything that I can think of.

If anyone can help, I would greatly appreciate it.

Your linkage should be mechanical. If your pedal isn't stcking to the floor then your cable is binding somewhere. It should be pretty straight forward and you should be able to figure it out with the car off and a buddy watching the linkage while you stomp on the gas.

Are you using a stock throttle body?

Stock ported throttle body.

Why would that matter? The throttle body has been ported for over a year and this has just started happening.

I didn't see any binding issue. I can go wot up to about 4500-5000 and it won't stick...but when I spin it around and past 6000, it sticks. The clutch is fine and my foot is NOT on the gas while shifting.

WTF?!

You are going to need to watch the TPS sensor with a scan tool when this is happening. See if the throttle is going shut.

The other thing to check is make sure the throttle shaft isn't broken or something like that. Take the air intake tube off and check it. See if you can get it to stick when you open and close it manually.

I have already done that. I pulled the lid and bellow/maf off and had a friend gas it and left off, gas it, hold it and let off, and many variations in between. The shaft is perfect, nothing gets stuck and everything shuts correctly. I even took the cruise cable off just to make sure it could be ruled out. I don't know what's up. LoL

I know the throttle body can't be sticking open after I've already let off the gas. I checked the spring and it has great pressure as well as snaps shup like a bear trap when closed.

I haven't looked at the TPS with a scanning tool but I do have a scan master. I can tell from there correct?

As long as it reads throttle position.
Is there any way that you could get on a chassis dyno? This would be able to duplicate the situation without being to dangerous.
