Ford is an iconic American brand we enjoy working on. Most engines from 1997 on will eventually have COP’s (coil on plug) issues. Also, care needs to be taken when removing/replacing the spark plugs, as they are notorious for breaking off inside the motor. If your engine has been running for a few years and you’ve noticed a decrease in MPG’s it might be time for new high performance spark plugs. A small investment in the most efficient and technological advanced plugs pays dividends when gas prices are as high as they are now. We have also seen quite a few problems with transmissions slipping or shifting hard. This is especially common in the Ford explorer. Overall, Ford makes quality automobiles, but higher mileage cars and trucks come with typically problems we are familiar with and have experience diagnosing and repairing.
