car was driving fine. stopped at a light took off made a turn and it started to spudder for about 30 seconds then died...
first though was gas...either out or fuel pump but both are fine....

we checked the coil according to shoebox and all was fine...
i replaced the coil with another same problem
replaced the pcm same problem
checked and changed out the opti harness

still have the same problem, any other ideas?

 

Did you check for codes?

Did you verify fuel pump operation with a pressure test?

 

what fred said

possible opti failure, I'd say rotor but more common they just shut off when a rotor shatters not a sputter
