I recently changed my rear valve cover gasket, and in doing so broke the right fuel pressure vsv(the blue one). My question is would this cause sluggish off the line performance and a check engine light? We super glued the piece back together till we could get to the dealer, but it is probably losing some vacuum, it broke in the plastic end and i think there probably was some sort of check ball in it before that may be missing?I just think this car should have more pickup than it does? Can this part be bought aftermarket? thanks!
