Kinda wierd issue..... car picking up the worse the air is

Well thinking about it more, I guess going progressively quicker wouldn't be affected by any changes. Comments about lean don't add up either. Would've been lean last year, too. I can understand something causing progressive slow down, but quicker? Thats a head scratcher.

Exactly

Got to thinking..... i had the car professionally rewired over the winter. Everything spins quicker, added new MSD box, starts now like its 16 volt
Guess i should check fuel pressure, etc. t
