ok....plugs changed, CTS checked...CTS is good, no change in how it runs...its really fucking wierd...ok, when i first start it...horrible idle..can't rev it without it nearly dying because of hesitation/misfire...then at the same exact time everytime during warm up, it does a little rev by itself and the idle smooths out to perfect, can rev it fairly well without a hitch...but just not able to got over say 60-70% throttle....so whats next?? FPR? IAC? TPS? what????????
