Hi all,,,Just pulled off the vacuum hose to the EGR valve on my 83280zx and found that someone has blocked it with a screw and then put the vacuum hose over it preventing the EGR valve from operating..Does this matter and what will it do to my milage and power???Another question.....Just put a new Alternator in and sometimes at idle the voltage on the gauge drops from14.5 back to 14 and the rpm needle jumps up and down a little and if I have my indicator on it flashes slightly faster than normal...The whole thing goes away when you increase the revs...Could this be the belt not tight enough???Thanks for the help...
