Hi, we just recently purchased a 1999 S70 turbo. I keep getting a random misfire code.
During some acceleration and during some sustained RPM's the Check engine light will flash and then read as a P0300 code. While observing the engine under run when the code flashes the Fuel System 1 will display OL Fuel system Fault then OL fuel system drive. Then the engine will idle fine and the light will no longer flash.
I did change the spark plugs with OEM plugs. And cleaned the MAF. Any other help you can give me would be appreciated.
have the same problem?
