idle issue G4 P/P evo 1-3

Recommended Posts

I have an issue where if my idle is lowered to pretty much anything under 1500rpm the car will idle lumpy and also causes it to back fire constantly on de accleration.

The car has an aftermarket intake with a 90mm Throttle body using a non sprung nissan TPS. I have tried calerbrating the TPS as stated in start up instructions but does not seem to change this.

Can any one help?

Thanks in advance

Could be a vast number of things to cause this.

Check for air leaks, correct mixture, correct ignition timing, correct cam timing

A must on wasted spark applications is resistive plugs.

Are you running cams with a big overlap?
