Car wont start without
I have 5.3 with ls1 intake and the car wont start without pressing the accelerator and as soon as let off the car turns off. I have checked for vacuum leaks. the plugs are black as can be. i am running a maf sensor. we did notice that the o2 sensors dont seem to be working right with a scanner. i did buy them from the dealership. they are new. the computer is not throwing any codes.
