LT1 Starts and Dies...?

Been having a problem with car just dying while driving. Only did it about 3 times, then I was having a problem with it starting... Now it wont start at all.. I replace the Opti Harness and it does the same thing. Sometimes I can unplug th harness from the opti and plug it back in and it will start, but Idle very rough and as I watch the RPM gauge, It jumps up and down then dies... I noticed where the harness plug into opti, there was corrosion, So I cleaned it out and NOW it starts everytime but dies right after...

I always find other issue so it ISN'T the opti, but Im leaning toward it now..
It a GM Performance with about 23k miles..
Mods in sig..

Thanks
Kris

I remember my RPM needle used to jumps around when the opti had died. I found oil inside mine, all over the optical sensor (like it was dipped in a bucket).

Have a look for any leaks behind the opti perhaps?
