P1141-Abs system related fault
P0300 -misfires detected
P0301 -cylinder 1 misfire
P0303 -cylinder 3 misfire
P1606 -abs system related fault
P1127 -bank 1 fuel system too rich
P1129 -bank 2 fuel system too rich

You may want to start erasing all the faults and seeing which ones come back. Thats alot of faults to deal with. Those abs faults trip sometimes when the abs control module is bad. Check for faults in the abs thou.
Fuel system to rich faults are usually caused by bad mass airflow meters but could be caused by anything that would cause to little air or too much fuel to enter the engine. Misfires can be caused by an engine running on the very rich end. You could also have an ignition problem causing misfires.
