random multiple mossfire when cold
tested coils, all within spec. replaced anyway thought maybee heatsoak and carbon tracing. cleard up for a bit. then back when cold. put dielectric grease in boots. still missfire.new plugs cleared for a bit, still miss fire. lean code. one bad CCV valve. replaced. cleared for a bit. biggest improvement was clean Maf. cleared for a while. then put premium in it. no difference when cold. sprayed allover engine to find vac leak. Nothing. still stumble when cold. when warmed up, no codes. no oil in plug wells. maybe enough in each to soak a Qtip. this thing runs like shit when itis cold. no exhaust smoke.......?!?! any suggestions?
