Check Engine Light

  • 1999 LEXUS RX 300
  • 6 CYL
  • AWD

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.

Do you
have the same problem?
