Take the chip out of the ecm and make sure there is no corrossion on the pins. Also make sure there is no corrossion on the plugs where the cables plug into the ecm. I would take the ecm out of the car by unplugging both connectors and start inspecting everything.

Hope this helps
When I get home, I'll pull the chip and check the connections. I'll also check the ECM plugs for issues. The way the car spits and backfires sounds consistent with what you are saying about the ignition module. I checked the coil packs last nite and the resistence on them were in range according to GNTYPE.ORG

Should I put the stock chip back it to see if it changes anything? Currently theres an TT street chip in it.
