Checked for vacum leaks every where there are none Rest pressure is good so I am thinking the injectors are still good what do you think?? Is my distributor just no good?? The valve thing was just a shot in the dark pretty sure thats not it (rebuilt over 300 engines in my life thus far but that does not make me an expert ) The miss is most noticable at idle but If I am outside the car running up the throttle by hand I can hear it just slightly at most rpm ranges. Cam timing is perfect! any thing else guys and gals?? I am sure it is something simple but what and how expensive
