last week i threw in some 50lb delphi injectors to replace the 440s that were in there and now it keeps popping at idle for some reason. Everything else is the same even the a/f. I replaced plugs cap rotor and the only way it stop is making the car really rich like 12:1's. The only thing i can think of is a bad injector in which one cyl is lean and the a/f reads fine because im dumping more fuel in all the other cyls. Does this sound right? and other ideas?

 

Sorry, I have no Idea but I am curious of what you are using for Fuel Management..

 

i think he is using the aem ems unit for his ecu setup

 

yeah aem ems but i really doubt thats the problem. My suggestion above is the only thing i can come up with but i really hope its not that cause that would mean i would have a lean cyl even under full boost.
