i got a 90 crx with an ls-vtec. pr3-4 head. the idle is at 2100 almost all the time. i adjusted throttle body screw, work minutely for a few days...now its useless. checked for vacuum leaks...none. the only thing i can think of myself is tps. is there a way to adjust? or do i need another one. which do i by my crx is a SI. do i try to find one of those or get a LS one. any other suggestions. also im slow so i will need detailed instructions. thanks everyone
