Engine misfires

1997 Ford F-150 mileage: 138,500. My truck has recently started what appears to be a miss; it mainly happens after the motor has warmed up and is under hard acceleration such as passing. However, this does not always occur. Any help or suggestions would be appreciated.

If a major tune-up has not been done recently, this could be the cause of your problem. Replace the spark plugs, plug wires, fuel and air filters, etc. Also, replace the oxygen sensor. In addition, service the fuel injection system. Clean the carbon deposits from the throttle bore and idle passages.
