Message	between a neighboring cylinder (cylinder 2 is probably the easiest) and repeat the test. If the RPM is not affected by cylinder 2 (with cylinder 4's coil pack) then the coil pack is bad. If the RPM is not affected by cylinder 4 (with cylinder 2's coil pack) then you have to move forward with more testing; -Check the resistance of the #4 injector --Bad result (OL or 0 ohms): Injector has failed (replace all 6 with a new style kit from Bernie) --Good result (10-14 ohms): perform a compression test. ---Compression tests good: Noid light to determine if the injector is receiving proper signal ---Compression tests bad: Leak down test, address issue. ------------------------------------------------------------------ 1992 300ZX NA 5 Sp (Dead) 1990 300ZX NA Auto 2+2 (Dead) 1990 300ZX TT 5 Sp (Est. 400 HP) 1990 300ZX TT 5 Sp (Est. 600 HP) 2004 G35 Sport 6MT (DD)
