jdhawes and I have had a recurring Check Engine Light problem. Both of us have had our injectors replaced twice. Both of us have had the s-s-s problem as well. We are told that the gas in Oregon is to blame for the CEL, though I suspect that the law requires Volvo to sell new cars in Oregon that can run without problems on the fuel sold in Oregon. I have had my intake system cleaned, including valves and ports decarbed at 12,000 miles. Dealer says the gas is to blame. He also says the gas in Washington is also a problem. Any other Oregon or Washington owners with similar experiences?
