i checked out the opti harness, and, im not getting spark out of the coil. There is no signal getting to the ICM to fire the coil. So, im pretty sure its my opti.

You could always verify what dtc codes are showing up if you have a scanner to know for sure its the opti if you dont want to wait until tommorrow .

well guys, tore my opti off today and checked it out.

I think i found my problem




when i took it off, there was coolant EVERYWHERE inside.

The seal around the top connector was completely missing, and there was a lot of rust-particals floating around inside there along with a lot of dirt/grime
