check opti harness at opti then where it hooks to main harness. well sounds like your getting spark since its loping, check n make sure your plug wires are right then check them again.

Check coil wires if your running an aftermarket coil. My msd never allowed the harness to plug tight and burned the wires to the coil from the icm.

And x2 on plug wires.
