opti is pretty much brand new.

coil is stock.

it started acting up after a heavy rain one day before then its ran perfect since i put this opti in.

im throwing P0117,P0200,P1371.

so its either the coil or the opti.

If the problem started after a heavy rain it sounds like the opti got wet. I know its a
pita, but try taking off cap to see if inside is wet and also wiring harness plug. Also is your almost new opti a factory one or one of the cheap flea-bay models. Personally I
use an MSD opti. They have eliminated the water intake problems around where the wire plug is by making it intergral with the unit. And the cap is sealed better then a factory opti.
