My check engine light keeps coming on and off at random times. The truck continues to run smooth with no apparent problems. Went to auto zone and they checked and said possibly the mass flow sensor might need work. Anybody else have this problem and what exactly is that. Thanks for any input.

Well, you'd get a better shot at diagnosis if you have the specific code number in hand.

So, we can't help at this point.

Get code number and come on back.
