Message	by pulling one coil plug at a time, see if all cylinders cause a drop in RPM when pulled. If so, then your injectors, coil packs, compression all check OK (maybe not great, but at least functional). This would lead me to believe it is an electrical issue (corrosion, bad sensor, etc) If one of the cylinders doesn't drop the RPM, swap coil packs between a good cylinder and repeat to determine whether it is related to the coil pack or the cylinder. ------------------------------------------------------------------ 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)
