I have a 2000 Civic with a GSR swap. but my idle and throttle are all messed up. when u start the car its ok and when ur driving its ok. but after it idles for a little while the idle will go to 1500 rpm's and then the throttle is all funny when u try to drive, it becomes extremely touchy. i need advice!!!

my car has the same problem............... but everybody told me it either might be the vacuum leak or IACV

 

check the iac
check your timing

which ecu u using?

i got a gsr in my si

 

question for you:

DId it start doing this on its own?
or did you do mods or adjustments to it?
