No power today. get's you there and back but grandma style. Reset apps by disconecting battries and leave key on over night or am I buying another TPS? HELP!

Codes if any?
When resetting the APPS you also have to turn the key to run (without starting) after reconnecting the batteries and slowly press the throttle pedal to the floor and slowly release.
Sounds like it's in limp mode.
Check for codes.
