CHECK ENGINE LIGHT

1999 Lexus RX 300 • 6 cylinder AWD Automatic •

1999 Lexus RX300 running rough check engine light came on and I had it scanned. The following codes were given: Po300, P0301, P0303, P0305, P0171, P1349, P1155, P0125
Now with that said this is what we have done
replaced 2 02 sensors,
replaced coolant temp sensor
changed out plugs and put in iridium(SP)ones
replaced air filter
cleaned MAF
cleaned OCV
car is running really rough, and CEL is still on.
