I have a ford 2003 f150, Within a month ago after starting the vehilcle it has a rough idle to sometimes dies out. When driving and accelerating there is no problems. Standing still the vehicle starts acting up.
Engine light came on and went to auto store they used a computer to see what codes came up, 3 codes and indications came up.
Mass air flow
Oxygen sensor bayes 1 and 2
poor gass,

I have replaced each item listed above and cleared the code from the the vehicles computer but still to this day same issues.
Do you
have the same problem?
Yes
No

Sounds like intake manifold vacuum leak. That is about the only thing that will cause all of your symptoms

I agree with mastertechtim. It is definetly a intake leak. For it to cause a mass air flow code, though, it would have to be a massive leak. The PCV hoses are prone to deteriorate. Check for large leaks, you may even be able to hear it.
