If the codes are there there is a problem. The longer you drive with codes illuminated the longer the problem is occurring and the more potential damage is being done to other components,
Someone will need to DIAGNOSE the systems involved and come up with an answer as to what has failed, not just guess and throw parts at the car. Accept the fact and spend the $$ to get an answer from a reputable shop. Cheap is not good in this case.
