HESITATION AND ROUGH IODLE

1998 Ford Ranger • 13,500 miles

The truck start fine after I changed camshaft sensor. Truck has a rough idle and hesitates while driving. After supposedly fixing problem same problem comes back after 4 to 6 months. Done tune ups. Changed crankshaft sensor, camshaft sensor, ignition coil, #4 fuel injector, changed wires and plugs with factory parts 6 months ago and it is acting up again. What is the problem and why does it come back every time. Thank you for your response.

Have you checked the engine for vacuum leaks, especially around the intake?
