I just installed a throttle body spacer in my 02 accord ex automatic and now when i start my car the rpm shoots up 4000 and stays there until i take it to drive or reverse and then it drops to 2000. when stopped at a light the car jerks forward due to the high rpms. what do i do to lower the rpm.

 

first of all remove the spacer... it doesn't nothing for you, waste of money IMO.

Second, once the spacer is removed and the car is re-assembled see if the car is still having the high idle. Also, it may be a good idea to use a new throttle body gasket on re-assembly.

and please use a better thread title the next time, "help!!!!!!!!!!" doesn't exactly tell people what the thread is about.
