Mass airflow sensor problem
I drive a 95 T-Bird w/4.6L and have been having a problem for the last month or so with the Check Engine light coming on. The stored codes are 171 & 174 -- fuel trim system lean condition for both banks. I thought perhaps the injectors were dirty and ran a couple bottles of cleaner through the fuel system, but to no avail. I finally succumbed and took my car to the dealer, where they diagnosed a faulty mass airflow sensor with a $500 estimate to fix. Since they didn't have one in stock, I'm now researching my options to repair this problem to see if there's a more reasonable alternate to biting the bullet. Any suggestions out there? Thanks in advance for your help.
