Hi All

OK, it wasnt the converters,or anything to do with the exhaust, a total backflow(?) exhaust test was done, and it had no problems. The shop owner said it has to be in the computer, or something.
It is back at the smog shop(a friend) and he is going to try to figure it again

Back to the problem;

It seemed to happen slowly to begin with, as I was on the highway. It was real bad on the hills. It seems to go away(for a minute) when the motor is shut off/restarted. It did seem to go away after I used a rubber mallet on the cats.
After the restart, it seems to be a time thing, as it seems that if I do a restart/go, or if I restart at a red light and let it idle till the green, it will only run good for less than a minute, either way.

After the rubber mallet abuse, It Did run good for the rest of the day, but the next day, it was back to the misfire.
