A few weeks ago i was having mass airflow sensor issues on my lbz. I fixed the issue by replacing the sensor. Recently a different maf issue has come up. After investigating i found that the dealership that i had my truck to messed up the ecm connector. Specificly the #18 pin which is maf. It looks like someone jammed a test probe in the little square hole. I confronted them but they "Did no such thing, and theres nothing we can do". Any ideas on a fix?
