Will not start its firing and getting gas if you hold your foot to the floor it will start but wont idle?

It sounds like your vehicle may have a fuel delivery or air intake issue. If it starts only when you hold the throttle down but won't idle, it could indicate a clogged fuel filter, a failing fuel pump, or an issue with the idle air control valve. Additionally, there could be a problem with the throttle body or an intake leak affecting the air-fuel mixture. A thorough diagnostic check is recommended to pinpoint the exact cause.
