Why must you hold down the gas pedal when first starting your 1994 Explorer XLT in the morning?

Battery problem! Battrey was replaced...problem still exists! I have a '94 Explorer and I can tell you, it is most likely NOT a battery issue, however it could be a number of things ... Throttle Position Sensor (TPS) is bad, fuel pump is going out or simply clean the air filter are a few suggestions. TPS is a little spendy, I think mine was around $70.00 at a local car parts store.
