No Idle Curiosity

She said that when the car wouldn’t accelerate, she could turn it off, restart it, and it would be OK for an undetermined amount of time.

F-150 Throttle’s Sensor Goes Amuck

Seemingly subtle variances in signals from sensors can trigger major changes in fuel and emission controls.
