Hi

I have a 01 gsr with most bolt ons, cai/tb/im/h/e/and no cat. awhile ago i got rid of the cat and replacd it with a straight pipe. Thats when i first seen the check engine light come on. Just recently I got the JG edlebrock throtle body, now i have a problem! I know when the check engine light is on it throws code, but now my idle has a mind of its own. It goes up and down from 1000 to 2000 (most of the time 1500).

I was wonder now that my ride is doing its own thing, if i were to get a new ECU like, Hondata, or skunk2, will that fix my car from throwing codes cause it has an all new computer?

help, thanks!
