Seebee, you are dealing with "winter blend" of Cali's gasoline. Thanks to Wild n Crazy,you make enough power now to notice.PM him,betchya he has an answer.
Thanks, Definitely noticing it more after the rebuild. But it also makes my wife's Mazda knock and shudder too. And even stranger is that it is only that Chevron station. There's one further down the street that hasn't given any problems. It's almost as if they are diluting their product.
