i put i fully built b20 in my coupe and properly broke it in. now im working on fine tuning it.. but its turning out to be a headache. yesterday i put 440cc injectors, aem fuel rail, fuel gauge, fuel pump, and a chipped ecu programed for my set up. before i did this it also had a rough idle but not everytime. now, its just gotten worse and dies sometimes cos it ranges between 200 and 1100rpm.. fuels at 32-40. i cant find any air leaks, so whats going on? could it be becos my stage 3 cams? any suggestions??

 

 

Take it to a shop and a tuner.

i just finished putting a bigger fuel pump in it... and its perfect now , thanks though

 

i just drove it more and i found out it still does it spontaniously so you think its just the cams and the set up?

 

get it street tuned. not a mail order one... my b20 had the same issue
