whats the main cause of the P1357 58 code. what do i need to fix to correct this problem!

 

Misfires, P1357 - Front, P1358 - Rear. Start by checking the plugs and wires. It can be a hard problem to track down since it's intermittant and most likely you didn't notice any problem other than the check engine light indicating a dtc code had been set. The main thing would be listen for popping or backfiring to try and figure out just when it's happening.
