Loose gas pedal, i need to push accelerator farther in

put the accelerator pedal down at least twice ? While cranking the engine ? key on ? what ? Your vehicle has electronic fuel injection ,not a carburator . Pushing the gas pedal doesn't do anything The only thing if pushing the gas pedal to the foor an holding it there will put it into clear flood mode , shutting off the fuel injectors .

Start the vehicle, and while pushing down on the break put the vehicle in reverse and gently use accelerator to go back an inch or four. If that doesn't work continue to rock the car back and forth until the ebrake cuts loose

remove loose floor mats, (toyota H3LL)
get smaller boots. so you dont hit 2 pedals at once.

to a what.....

Failed Transaxle

How can you not know that ??

The pedal should NOT PUSH that cable - it SHOULD be loose. The pedal should PULL that cable.

Your gas line could be dirty, check your gas filter.

Is the check engine light on, and have you checked fuel pressure with a gauge ?
The most common cause of that problem is a faulty Throttle Position Sensor but it should set a code in the computer.

If it is running bad enough to be backfiring, the Check Engine light should be on. I would start with scanning the engine computer for fault codes.

Two symptoms here Keith, and I just had this, same car year and model. The pedal could either be a bit loose, check the cable and throtle. Have someone check, when the cars in neutral,they manually rev it, and watch the RPM's. They should go 3-4 as normal. If this is the case, and its not the cable or pedal, REPLACE spark plug cables and wires. Odd, but that was the fix to mine. Hope it helps.
