After I bought the car I got an after market air cleaner installed..A good K&N. They did not say anything negative regarding the air cleaner but here is where it gets ridiculous...When the airbox was opened a bug got in and shorted the mass air flow sensor and because I had "opened up" the air box and allowed this bug to get in I was responsible...For the record that was a year ago so the bug must have ben hibernating...What a LOAD of CRAP..
I have a call into Ford now to file a claim and will let all know how this plays out...

Not what you want to hear but Wetted Oil Air Cleaners can cause the Mass Air Flow Sensor to fail. Before Fuel Injection old school they were wonderful.
Now most Technicians have been trained to not recommend them. And in fact there are several bulletins out for shift problems drivealbilty and Service engine soon lights pertaining to this.
The filters oil mist travels in the airstreams vortex to the Hot Wire and causes the Mass Air Flow Sensor to give eronous Data " Althought the Driver never knows this " Or worse the sensor can fail.
If a Bug hit the sensor it is down stream from the air cleaner. This means the bug would have had to pass throught the air cleaner. That is unlikely unless the air cleaner was not seated properly. I have seen this happen often.
Or the bug was in the housing dead but coated with oil. Then the air flow moved the dormant critter up on to the mass air flow sensor at high air flow.? Ot the sensor failed and they are not wanting to warranty?
Many variables. I feel you fustration. Just giving you the facts.
