Well, after replacing all the injectors, KS, KS harness, every damn sensor I could easily get too, the front 3 coil packs that were cracked, and assuring good seals on my O-rings, the VE is still studdering randomly. Not nearly as often as before I changed the injectors, but its still doin it once in a while. Do those damn OEM plugs REALY make that much of a difference?

this is making me ill

 

Buy NGK copper plugs. ~$1 each. Platinum just extends the life of the plug, doesn't really do anything for performance. Go to NGKs website and cross reference our OEM platinum plugs, because I think they are different heat step than the VG coppers.
