Hi all. As the title states, my 2013 GT/CS does this thing when I'm cruising at lower speeds and RPMs. When my foot is held steady on the gas, it kinda cuts out or backs off a little, then recovers quickly; happens about every 3 minutes or so. It seems to improve a little when the engine is warmed up. My '88 5.0 GT did the same thing at one time in it's history and replacing the throttle position sensor fixed it. So my question is, does the 2013 GT/CS also have a TPS and might that be the problem? Would OBD reader show the problem? Or other ideas? Thanks.
