Check engine light started flashing the other night, but only when load bearing. Parked it. Took it to mechanic, tune up, spark plugs changed. Coils were done last year. The O2 sensor does need to be replaced. Mechanic not too familiar with Volvo. Could the sensor be what is causing the check engine light to flash? The tune up sucked up all my spare cash, so is it safe to drive?
have the same problem?
