I have a 1993 Nissan Altima that is not firing on the # 4 cylinder....I removed each spark plug wire with noticeable change except for the #4 cylinder....did a compression check all cylinders read at 125....changed wires plugs, distributor cap, rotor and still the same skip on #4....any suggestions...my thinking is a faulty distibutor....I tested the wire on the # 4 cylinder and it is getting juice from the coil.... but I cant explain or figure out why the skip

Hi there,

if you have checked for spark at No 4 with a plug earthed and it is OK, check that the fuel injector is working in that cylinder next.
