Check codes today. There where none. Pulled valve cover and looked at springs and they looked fine. I'm guessing you would be able to see broken springs and I didn't see any.

Computer says it has 67 hours on motor.

This set up has two coils (4 plugs wires per side). I'll check for heat on the next test run.

Other Possibilities:

Injectors
Kill switch
Plug wires

Not ruling out coils.

i would say plug wires. i had a problem with a little spuder and it was the wires. i would pull and reconnect wires and see if there any cuts or imperections in the wires.

Thanks for all the help!

Teague put it on the computer and says dirty injectors. I'm just going to change them all and stop messing with it. Back ordered until July though.

One good thing is that I found out my motor actually only has 67 hours. This thing is barely broken in. Should have some trouble free times ahead.
