1998 Escort Station Wagon Mass Air Sensor

  • 1998 FORD ESCORT
Over the last several days, my car has been running very rough. Yesterday, the service engine light came on. When I took it to the mechanic, he could find nothing out of the ordinary except he said my PCV valve had collapsed and he replaced it. He did say that this may take care of the problem but if the light goes back on and the car starts running rough again, he would replace the mass air sensor. He said he did not want to sell me the part if it was not needed. The car started to run rough again after a few weeks. I took it back and this time a different mechanic looked it over and said he could not find anything wrong. Even the history on the computer did not show anything. I guess I'm stumped. Is it difficult to replace the sensor by myself and how much does a sensor usually cost (stock)? Thank you for your help.
Do you

If the check engine light came on then the computer read the fault
the reading would of shown on the OBD11 reader
if you suspect its the maap sensor take it to a auto parts store and have it checked to see if its defective
after a check engine light indication you have to reprogram the computer you do this by disconnecting the negative battery terminal for 15 minutes other wise the computer tries to compensate for the prior problem even though it may have been rectified
Was this
