Hello,
Looking to get some help with regards to Idle issues. My father and I have put together a SBC 427, and had a basic tune dumped into it from a camaro so we could run it on the dyno. The small idle issue we have is that it will not start just by turning the key, I have to press down on the peddle to get it to fire. Once it starts, it idles reasonably well and usually around 550 rpm. We are running an LS1 ECM from EFI connection, and an aftermarket TPI from FIRST fuel injection. Not sure if the Idle air motor can't provide enough airflow for the tune or if we have to much fuel being dumped in during cranking. I have downloaded my tune on my laptop and looked around a bit but as of now, its all greek to me as i'm very new to this. Does anyone know of any quick things to test or checks that could help eliminate some possibilities?
Thank you,
Jordan
