    I think it's a fuel problem. If u really get into the peddle it straightens out. It's not like a plug wire electric problem.it idols good also

    Did you actually scan it for codes, or are you basing “no codes” on lack of an SES light?

    Fuel issue would (should) get worse with more engine load not clear up.

    90% of the time a missfire in an Lt1 ends up being the opti... for me anyways But I keep fresh wires and plugs on my stuff.
    Is it poping/backfiring or just going dead on a cylinder?

    Sounds like what mine was doing with my first opti...ran good under load but hesitated and stumbled off throttle. Went LTCC..all my little quirks I was having vanished.
