idk if anyone else have this problem but when your on it, and go to shift do the rpms suddenyl rise when you push the clutch in?? or when u get on it in first and push the clutch in do the rise?? i dont understand it. i think its just the way i shift, but sometimes if i shift slow it wont do it. does this happen to anyone else or am i retarted and just push the clutch in to soon.

ive ben driving stick for years and no how to drive i just havent had this happen to me in all my cars except my evo ( not my 03 cobra, 98 cobra, 96 supra)

help??

 

It could be Idle Stepper Control Valve or a dirty throttle body. I had the same issue, I cleaned the throttle body and bam...problem solved.

 

does it rise when you are in a complete stop and turn the wheels? do you notice change also when the AC is on?

it might be your Idle control valve, like mentioned above
