Believe it or not this issue is still un-resolved. Took it to the shop for them to fix it and they told me it was a combo problem of my belts as well as the belt-tensioner on the supercharger. Granted there is major play in the belt tensioner when a quick hit from the throttle is applied. But with them breaking my hood release cable as well as some other things I said forget this place I’ll do it myself. I did replace both belts as well as the belt tensioner. No change whatsoever. So I’m thinking of maybe taking the supercharger off and replacing the gasket. Never done this before but I am confident I can do it with a little help from this forum. So what do yall think, should I do it? Or is it a waist of time?

Well it'* inepensive and an experienced member, sorry forget the name and too lazy too scroll, has resolved a similiar complaint by replacing the gasket. I think I understand the explanation of why a blower gasket would cause the drivability problem, but I'm not going to try it until I monitor all my inputs and see if I have an obviuos problem. Replacing the blower gasket would be easy. The hardest part will probably be removing the old gasket. I had two codes and one was an open in O2 sensor circuit. I found a butt-connector about 6 inches from O2 connector and soldered and shrink wrapped the connection. I also replaced the sensor because it was non-oem and it wasn't swinging voltage the way I would like to see, even for a single wire O2. I still get the code 13 at WOT, When hesitation starts. The CEL comes on as soon as hesitation starts and goes out as soon as I back out of throttle. I'm leaning toward a faulty ECM, only because I've checked out the enitire O2 circuit from sensor to ECM and there are no opens or shorts in it. I need another day too play with it. Haven't tried trouble shooting the EGR code because don't believe it too be the cause of incident. It is easy enought to take it out of the equation though for a quick test drive. If you change gasket please update progress.
