2010 Toyota Tacoma cruise control problems

Were pulling out and smell of gas filled up the cab, jerking occurred. Experiences of intermittent acceleration had been occurring for a very long time as been made aware of recently. Smell of gas has been overwhelming. Vehicle now parked outside and will not drive until it can be fixed or replaced, have been warned of potential air bag failure in japanese plants found last week in this model. This vehicle is the only car we have, paid on it for a very long time.

While driving on interstate highway at the posted limit, the vehicle set speed would sag by 2 MPH at the bottom of a hill as the road leveled out, then it would start up the next hill with a 2 MPH deficit. As t proceeded up the hill,it would downshift to maintain speed, then downshift again to 3rd gear and accelerate over the top of the hill in 3rd gear until it would overspeed, exceeding the set speed by 3 MPH as it went over the top of the hill.
