I had it running good,there was no vacuum leak and it was just bad coils and plugs,but now its doing the same thing again after i opened it up to see what it could really do last night, I got the best quality stock coils i could get and i got stock replacement AC Delco spark plugs,my wires seem fine. I could smell burning rubber really bad,I think part of my issue might be that who ever put the smaller pulley on the supercharger didnt get a smaller belt like they should have but I'm not real sure what my whole issue is. any ideas for me?? oh and I'm running 93 octane fuel
