The title says it all, every time i shift my RPM will shoot up just from pressing the clutch in for each shift. Any ides on a solution? If you need anymore information I will provide all i can. Thanks

First, you better tell us what you have. Year, model, modifications (if any)...

Wow, sorry it's a 1978 280Z with 5 speed tranny.

all stock

Sounds like a sticky throttle, which could have several causes. The throttle body could be gummed up from blowby residue. Or the dashpot could be sticking.

You're still not providing much information though. How long have you had the car, did the problem just start, does it happen all the time or only when warm, etc.?

The car has been doing it as long as I have had it, which is about 3 months but only maybe a month and a half of solid driving. This occurs every time that I drive regardless of temperature of the car or the environment.

The dashpot is designed to keep the throttle from closing fast. If it sticks or is adjusted too far down, it will hold the throttle open too lng and your RPM will rise between shifts. It's the round thing mounted on the throttle body with what looks like a vacuum fitting or a plastic game piece mounted on it. Remove the two 10 mm bolts and take the whole thing off and see if you still have the problem. If the sticking goes away, then you can either clean up the dashpot or leave it off. I like having it myself, it makes for more relaxed shifting when it works right.

I've also had the inside of the throttle body get gummed up, and cause throttle sticking when the engine got hot. You can clean that up with carb cleaner, but you have to take the AFM boot off to get in there.

Alright thanks, I have done a bit of searching about the Anti stall dashpot and seen that some people have taken them off while others leave it on. I'll try that tomorrow before I head off to work, and I've already cleaned the inside of the throttle body.

On my '77 dash-pot there's a small brass screw under that white cap, very small, jewelers screwdriver small. Spray the protruding rod with some slickum and adjust the screw. Mine works good with about 1/4" movement on the throttle mechanism. If that's the problem. What about unplugging the BCDD for a test drive? It has 1 wire that has a bullet connector below the coil.

The problem was the dash pot. Removed it and now its fine, thanks for the help guys.
