Need some help with a sticky throttle. Ok, I had this problem last year as well before the motor broke.
Low RPMs, when you shift its fine, the throttle drops and everything works fine. When you get up to around 4k or so you push in the clutch pedal and the rpms just do not drop. I don't understand it at all.
Say I shift at 2500, no biggie, push the clutch in the RPMs fall. Then say for the next gear I want to go t o say 4500 just easin into it so it doesn't build boost, I push the clutch in, and it stays right at 4500 RPM, doesn't climb doesn't fall...just sits there. I'm pretty sure the by-pass is open as well, since it is open you can hear it pretty good.
I really don't know what to do.
I've had a second spring on it and it still did it. Someone said to put one facing forward instead of back, thats the only thing I haven't tried yet
The car is a blow thru design (LT1 car), with at D1SC blower, twin intercoolers and the by-pass valve is open to atmosphere and it is open under vac. I'm still breaking the motor in so I haven't gotten under boost yet but last year it didn't matter. I did put one more turn on the return spring to give it a little more force. Still nothing.
Ideas?
The only way I can get it to not do it is by giving it some pedal then snapping it shut when I shift and then it will drop.
