Would a faulty fuel temperature sensor cause a rough idle? When I press the accelerator, it quiets down. For reference, the sensor code is p1083.


It sounds more like a vacuum leak. That could explain why the idle quiets down when you press the accelerator. Other reasons for a p1083 include a MAF sensor, a bad fuel injector, or another fuel system problem that may cause low fuel pressure.
