*Update* Hard Starting Problems
Well after having a hard time starting the car,(Car has a new 355, hotcam kit, wires, opti, coil, fuel filter) I went and had the fuel pressure checked. At startup, it goes to normal, at idle it holds about 42 psi. Under wide open throttle it falls down to 36.5 psi! I also looked at the first 2 plugs on the passenger side, they are pretty carboned up, one was actually a little damp above where the threads start, which would explain why when I started it, it ran on 4 cylinders until I revved it above 4k rpms where they all finally fired. So I think the plugs are my starting problem, not to mention the computer is untuned. As far as the fuel pressure dropping, that would explain why it misses slightly under load. Could this be the FPR, or possibly the injectors? They are all stock with 140k on them....thanks for any further advice
