well what are your mods exactly..but 1st things first check power transistor,plugs,wires cant imagine tune issue,didnt see tuning software in your profile.

mods are as profile states. I have a 190lph autolite plugs and ngk wires they have 10-15k on them. other than that nothing.

is there any way to tell for sure what the cause of this code is? I have searched and there are so many different solutions that worked for people.

any ideas?

try checking your spark plugs and there gap

good already checked plugs and wires

well today I took it into the shop to hook it up to an OBD-II reader (not just a p code reader) and through some of the diagnostics on there everything looked fine. So I turned it off and started it up again and low and behold it started and ran fine and I have yet to have the light come on again since clearing the code...
