Hey...my service engine light came on last night right before the game... heres whast weird the light came on and then my truck started idoling right... kept one constant rpm wasnt doing its lil shaking things and drove better... better throttle response and a lil more power it felt like... but does anyone know what might of caused it to pop on like that

 

Might be the computer went into safe mode on one of your sensors. Go to autozone or whatever and have it scaned bring the actual code nember back do a search or post the actual code and someone will help you.

 

K thank U
