any recommendations on where to start with fixing these problems I’ve been told to replace my tps which I haven’t done yet but probably will, but it does have new spark plugs and coils. Engine does not run necessarily rough only when cold started it can feel a misfire here and there, engine seems normal while driving speed limits and babying it but once I get over 2500-3000 rpm it misfires and starts jerking, but it’ll still go pedal to the metal no problem
