I replaced my opti, and now my engine doesnt run smooth. Sort of like a sputter. It ran like this when a spark plug wire burnt against the header, then i replaced it. After the i did the opti and now its back to running like sh*t. Any idea what it is...i think its ignition related.

Check your spark plug wire routing at the opti. It's the #1 mistake people make.

What brand of Opti...

Elco85

could be a vacuum line, check the lines at the distributor and on the intake, one could have came loose from up top
