Question
where do i locate the mass airflow sensor and how do i find the positive and negative wire so i can remove them to replace the with a chip

Answer
The mass air flow sensor is between the throttle body and the air filter.You can use a meter to find which is pos and neg.The pos is usually red and the neg is black but it varies on different cars.Using the meter,switch on the ignition and insert the probes for each wire ,if its pos it will read 12 volts if its neg it will read minus.
