Okay, stock block .030 overbore, new eagle rods, forged K.B. pistons, Trick Flow #1 Cam (221/225 dur. @.050,.499/.510 lift), AFR 165's, Typhoon intake (port matched to heads),73mm C&L meter, 24# injectors 42psi, 65mm TB, 1 3/4 longtubes w/3 chamber F.M. cat-back.
Problem: In the morning it runs great, I can drive it for 1 hour, or 15 min. to work smooth as silk, but when I shut it off, no matter for how long, 2-3 hrs, or start it right back up and there is a slight skip or miss, most noticable in high gear under load at low RPM's. It has to set like 12 hrs (overnight) to go back to running right, it does this EVERYDAY!
I've tried new plugs, wires, coil, cap & rotor, new O2's, even tried a diffrent CPU, it's like somthing gets hot and causes it, but why does it run good until I cycle it off? I've looked for bad grounds? code scanner came up O2's but that did'nt fix it.
Anyone ever ran into somthing like this?
HELP!!!
Thanks
Wes
