First, take it to an auto parts dealer and tell them the situation and ask if a diagnostics test will help determine the cause. Here are some things that may cause this:
(The DEQ (or test place) should have told you what to replace)
1. O2 (oxygen) sensors
2. catalytic converter
3. emissions unit in the engine compartment
(these are usually located on the passenger front side in the corner) depending on the vehicle make, model.
Please let me know if you need further assistance.
replace the pvc valve and have the egr valve replace.make sure the vacuum hoses connect to egr valve and pvc replace.change air filter.all those things will cause high emission if not working properly.cause you to fail smog test.
Tune it up and replace the 02 sensor that keeps setting the codes bank 2 sensor 1. Have your oil and filter changed right before you go for a retest to. That will clear up 3 codes P0300, 0155 and 0154. You might have to replace the fuel sending unit to get rid of P0463 but if the gauge works OK I'd leave it alone.
