I can hear some dull "rattling sound" - seems to be coming from the top right side of the car - sounds like "loose fitting" ? It happens when I am driving on "uneven roads" - anyone has similar experience?
Please advise!

Thanks!

Codes are Boost pressure not sufficient, Cat below threshold and n75 open. Ran a readiness test and the following failed; egr system, 02 sensor, ac, catelyst.. time to trade in?

Is there any oil on the dipstick. Has the oil minimum light, or pressure light ever come on?

Yes, the OIL light has come on, there is oil I change it regularly, I highly suspect the cat converter. Expensive part to eliminate
