car bogs down when i give it gas

[RPD4g6497]

so do you have ne ideas of what it could be

well i have definatly finally figured out what is wrong and it not good.... a broken or bent valve i can hear something banging around in the cylinder head and i have metal shavings flying out of my exhaust and if i hold the gas pedal to the floor flames shoot out of the exhust so im pretty sure its a valve or something related so now i must think about whether or not its worth tring to fix i think im just gonna swap the motor out with another 4g64 or sumthin i have to get this car working its my only car!!
