Pick-up hesitates briefly on idle speed

My Pic-up hesitates for a few seconds on idle speed and continues to run fine. Then it starts all over again. NO check engine light. One thing I have noticed; the problem is becoming more frequent.

In addition to the above, also try cleaning the Mass Air Sensor. it is located just past your air cleaner going back towards the engine. Just unscrew the to star bolts and you will see a small fillament when you remove the sensor. If it is not shinney and appears dirty, give it a qiuck blast of carb cleaner and then let it dry for a minute. Put the sensor and bolts back in and see if that helps. I have used this on two Ford Ranges and an Explorer. Seems to help a rough running older engine.

A slight hesitation after engine shut off due to engine running rich meaning not meeting golden air:gas ratio of 14.6:1 so fuel residue in chamber continue to burn for the last moment. The same rich fuel problem that was why you had to let gas off during acceleration. Need to Check out the O2 sensor Check out MAP sensor Good luck
