Just completed a 5.3l swap in to a custom car. I am having quite the issue with getting it to idle it starts and idles for 2 secs then shuts off. my first thought was vats but its disabled. now for the kicker i thought it was killing fuel so i started it then sprayed it some brake clean to see if it was killing fuel. well the idle dropped really low but it continued to run once i stopped spraying the brake clean it continued to run and idle just fine until i shut it off. I have changed the amount of time before it tries to learn idle and it will run a bit longer it still dies. the specs are Custom fabbed headers, ls1 intake, and 36?lb svo injectors. I know at gm pressure the injectors are 40-42 lbs they are white bodys. i have been beating my head against the wall for weeks with this thing please help me!!!!
