Richkrys Posted June 12, 2022 Share Posted June 12, 2022 I have a 2016 Legacy for about a year now and it suddenly started bucking between 1000 and 2000 rpms. Its fine below and above that but bucks and stutters otherwise. I cleaned injectors, checked plugs and coils and they seem to be fine. No check engine light comes up either. Any thoughts on this?

Greenmamba Posted June 12, 2022 Share Posted June 12, 2022 Throttle position sensor. You have a drive-by-wire system which means the throttle is measured by electrical measurements of how far the accelerator pedal is depressed, thereby operating the engine speed electrically (used to be cable connecting the 2). It could have developed faults, meaning the pedal movement isn't being translated accurately. If it's the problem, replacement of the tps may be needed.
