Anybody in or around Houston have LT1 edit or a good scanner that wouldn't mind helping out a fellow Fbody owner? I'm trying to track down a pretty bad stumble/misfire, and I don't want to pay $75 or more from a dealer. I've used the basic ones at Auto Zone and places like that before, but they won't pinpoint anything. They just say random multiple cylinder misfire or something else generic like that. I would really apprecaite it. Thanks.
