Rough idle

Post by bstdhybrid »

I can get the car to start but the idle is rough. You can hear small popping sounds(running rich?) When I take my foot off the throttle it just dies out. I'm using the greddy base map w/ 650 injectors. I'm using rc 750 saturated injectors. I changed the injectors on the map and thats it. Any pointers on how I can get it to idle smoothly so I can drive to my tuner?(1hr away). I have an areomotive fpr and set it to the lowest pssible setting to keep it from running rich. I'll upload a datalog if you need me to. Just tell me what sensors you want to see. Anyhelp would be appreciated.

The most likely cause is too much fuel. You will need to return the fuel system to stock.

I currently have a return style setup. So I need to convert it back to a returnless system? I thought the purpose of going with the return style system was because the returnless style system limited you to how much power you can make.
My goal is to make around 340-380whp. And 380-420 with race gas whenever the 3 bar map sensor comes out. So all I need for my fuel setup is 750's,walboro 255lph intank pump, kpro and a retunless setup?
