does anybody know what could of caused this problem? i have an aem fuel rail with rc 320 injectors which is about 10 months old.. anybody know how i can fix this?? thanks in advance

 

dirty injectors?

how did you decide that 2 cylinders are running rich and the other 2 are lean?

 

2 of my spark plugs has dark deposits, the other 2 is really white.. ive noticed a leaning problem when my air/fuel gauge goes to lean when i floor it.. how do i go about cleaning these injectors, can a machine shop do this?? i dont understand how brand new injectors can get dirty so fast..

 

try adding like 3-4 bottle of good fuel injector cleaner into like 1/2 tank of gas and drive it until it's amost empty and see if that helps.

if not then your gonna have to send the injectors out to have them professionallly cleaned.

i think RC can do that for you........
