Alright i can't get rid of this engine miss. It's noticeable at idle and when i rev the engine its slight. I have brand new NGK plugs, Accel Wires, Cap, Rotor, i checked the MAF ground, Adjsuted the TPS, adjusting idle air speed dosnt help, proper timing setup, all new vaccum hoses routed, No EGR system as its a JDM engine but i have the sensors hooked up and vaccuum hoses hooked up to trick the ECU or whatever so i don't get CELS. I checked the ECU for non CEL codes, dont get any, and i'm ***** try changing the fuel filter and checking for intake manifold leaks tomorrow. Anything else i should try adjusting/checking etc? I'ts getting annoying and i need it to be running perfect to try and pass emissions.....Anything you guys can suggest is appreciated. I Searched the forums and se-r.net for help and foudn nothing other then what i tried. Maybe you guys have some tricks that got your engine running smoothe.....
