my 2001 lexus is300 has been having this thing where it sounds like its misfiring when i tap the gas pedal at around 2000-2500rpm. it only does it in gear and not when im parked or in neutral. i also noticed i have been idling pretty low from cold starts, usually it was around 1500rpm but now it idles at 1100rpm or lower. i just replaced my spark plugs and my coil packs
