Any suggestions, my daughter has a 2004 Crossfire that has the check engine light on. Emissions diagnosed the code as P2098. The dealer here in town looked at the vehicle and diagnosed it the left up and left downstream 02 sensors need to be replaced (at a cost of over $1200). My boyfriend bought the 02 sensors and replaced all four of them. He cleared the codes and the car was driven for the "recycle period" only to have the check engine light come on again with the same code? Any suggestions?

Also from what Emissions is telling me the code does not need to be cleared that once the correct diagnosis is found and the repairs done the check engine light will turn itself off without being reset.

Any help anyone can give is greatly appreciated.
