OK.....Nice weather so I ride up n down the mountain a few times. Its only 930 ft. SO....Its not a very big mountain! As I come down the last time I let the engine brake it a tad in 2nd. gear. All the other times I let it coast.I stop n look around a bit and got ready to head back home.It was slow crankin....Like it was not gettin enough gas.But it started.....As Im going up n down a few hills it goes back n forth between engine brakin and excelerating.All while im holdin it at one RPM. After I got back on kinda flat ground it quit and has ran great since.It has done this b/4 aprox. 3 years ago......Almost in the same spot! It is a 2014 ST with 30000 miles and I always run 93 gas. Anybody have any idea whats goin on? Kinda scared me.....Thought o chit......Its gona leave me sittin! AND......It has started showing 1000 more RPMS than its runnin on the dial.It is correct on the dig.gage.....It has done this b/4 as well.Anybody else have this issue? :yikes: TIA Tony
