After doing the mpfi swap i had a few problems with my idle, my cable was to tight and EACV was no good. I adjusted the cable and got a brand new EACV.

The problem i have now is that my car idles like **** and and back fires after the car has warmed up. It`s also slow returning to idle after the clutch is pushed in. When i start it in the morning it idles high like normal, comes does a bit, but it`s not farting and idling the **** when it warms up.

I know that when it`s cold it`s running in closed loop, until the O2 sensor reads the exhaust temp, so when it`s warmed up what would make it do that? The O2 sensor, coolant temp sensor, what else?
