someone did the swap for me 3 months ago...i have cia, exhaust, on a b16a. The problem is when I start the car and turns back off. And i start it again it runs but it idles up and down. Second problem I have is my vtec. I can hear the vtec kick in but there no increase in speed. the engine just gets louder and that's all. ive changed the distributor, fuel filter, tune up, oil change, but both of the problems still wont go away. i tried my friends CHIPPED pr3 ecu and that worked hella good. So now I'm wondering is it possibly my ecu or something else . and i raced a 90 integra ls and lost 3 daym times to it. he only had intake exhaust too. Please begging for help.
