so i went to the autozone and described my problem and the first thing the guy said was the intake manifold gasket could be bad since i did recently take off the manifold so i bought some carb cleaner and sprayed in between the intake and the head and the car revved up ALOT, to like 3000rpm. this damn ka has made a fool of me. i guess thats why they say to replace gaskets when you take stuff apart but im lazy and was like "uuuh, it looks fine, screw it." lol. so i replaced it and it runs and pulls just as hard as it used to, no misfires, no rough idles. still gonna get my vh built soon tho
