well after replacing the icm the high rpm misfire seems to be gone now it dies coming up to a stop or idling sometimes, when it goes to die if i try and save it by giving it gas it still dies i put my injector test light on and paluse is there and will brighten up when i try and save it from dieing but engine rpm doesnt pick up, new codes now are high res failure and low res failure that all points to the opti!!!!!

you said you've replaced the opti twice already, have you been using GM optis? That really sucks, has anyone else had to replace optis in such a short period of time or gotten opti codes?

I don't know much about the mod, but have you considered LTCC?

The first 2 the rotors feel off of,there are Accel optis. well i think the Icm fixed part of the problem and now i just got a junk opti. Right now the car is running strong just will die at a stop now and again.

well took the opti apart one screw feel out of the rotor again and i had put red lock tight on the screws before.
