Bad Opti? OK so i took 2 videos of my car acting stupid once again. It's backfiring alot under load, even at high rpm. also stutters really bad at cruising speed in higher gear.
I just did the thermostat and heater core in it, got a little bit, NOT much, of coolant dripped onto the opti. i didnt think it would be enough to kill it. but i guess, i've got a intake manifold leak as well and the oil is also leaking on the opti from above.
so here's a couple videos, make sure you turn your speakers up so you can hear it
let me know what you think it is, my brain is telling me opti....

Start cheap. Check if your elbow has any holes or tears and is fully on the TB. Get some washers and space the icm off the head. With your engine idling at night w no lights, pop the hood and look for fireworks - go one step further and mist water over each side to see if any wires are arching. Have you deleted the air pump and egr?
All of these can cause stumbling, hesitating, bucking, etc.
I'd hate for you to replace the opti, plugs, wires, icm, and remove air/egr (like I did) only to find a half-inch tear in the bottom of your elbow that was the source of all my issues

really could be a number of things.. icm, plugs fowled, wires arching, opti, coil, you just need to start with the normal test to eliminate fuel and spark. the free things. just dont throw parts at it and hope it fixes it and blow your money.. diagnose then fix
