Lol..... I took off the fuel rail and left injectors plugged 2 fuel rail & harness, then took off distributor so i could spin it by hand 2 check if one of the injectors was staying open or leaking. so I did and all 4 injectors are opening & closing none of them were staying open or leaking, but all 4 were firing @ the same time, don't think that's normal! is it?
