Is there anyway to test a MAF or the ignition coils? I suspect these may be my problem, but would like to be sure. Hate these guess type solutions. My car hesitates/surges and has an occassional miss on very light throttle @ 60MPH. Same issue in sport mode. Did all the normal stuff-TB, Cleaned MAF, unclogged Part load breather. Next step is plugs, and maybe coils. Any help appreciated.
