On the giving it gas at idle. I agree with regard to a carb/jetting/rich lean issue, but look to see if you have the PAIR system set up. I had a similar Roketa and had the same issue. Once I removed the PAIR system and totally simplified the fuel and vacuum lines the problem completely went away. Also, I'd check for a vacuum leak.

Good point, Ebuddy.
I didn't think of the emissions stuff. I had gotten rid of the evaporative system and bypassed the PAIR system (removed later) during the PDI.
