I've have had the code read @ Auto Zone, Advanced Auto, & the dealer the code was for the mass air flow sensor. All said that since it was the same code every time that it had to be the computer because the chances of getting 5 bad sensors were slim to none. So thats why the computer was replaced. Less than 24 hrs later the check engine light was on again & still throwing the same code. I was only charged for the 1st MAF & labor not the next 4. The computer & labor were not to bad, but still didn't fix the problem. I don't have money to throw away but the car had to be fixed. As it turns out it was a bad oxygen sensor & it was replaced the gas mileage is back to normal & the check engine light hasn't been back on.
