CHEVY AIR FLOW METER

2000 Chevrolet Astro

Engine Performance problem
2000 Chevy Astro 6 cyl Two Wheel Drive Automatic 91041 miles

The " Service Engine Soon" light comes on occasionally especially when revving it up to enter the freeway. I had it diagnosed by a friend and found that the problem is the Air Flow Meter. I haven't bought this part but when I'll have it, I want to change it myself to save some money for the smog test. My questions are: 1) Is it really the air flow meter that's causing the service engine soon to come on, coz the engine feels like being choked when I accelerate. 2) Where can I find the air flow meter in the engine? Thanks in advance and hope you can help me.

Hello .. thanks for the donation .. much appreciated

Without knowing the fault codes we cannot state it is the MAF sensor causing the fault .. But if your friend read the codes and the code stated MAF sensor .. it probably is the MAF ..It is a very easy repalcement part ..

Mass Airflow Sensor....Front of air intake duct.

Hi aspiringtech,

Thank you foe the donation.

Any fault in the engine management system would trigger the SES to ccome on and it could be the air flow meter or something else. What was the exact trouble code retrieved?

It could be a faulty part or a loose wire connector and before replacing the part, it would be best to diagnose the problem to confirm that the part is at fault to avoid unnecessary costs.

The symptoms do seem to be caused by the MAF malfunctioning.

Check to see if the air hose is securely attached and no vacumn leaks occurs between it and the throttle body.
