Bad misfiring problem
Well this been going on for a few days. The car starts fine and runs fine. Then when it gets hot it will start missfiring really bad, barely will run, (sometimes the SES light will come on sometimes it won't.) And then without doing anything to it just keep driving it will straighten up and run fine? It done something similar to this before and I changed plugs and it fixed it. But the SES light never came on and it done all the time. Anybody ever had this happen? Could it be something simple? I'm thinking probably optijunk.

Had the same exact problem. Check the cable from the coil to the opti. When I pulled mine off it was all corroded (white powdery crud). May not be it but worth checking out.
