Folks, seeking wisdom here...

I need to know exactly how I should go about checking my Mass Air Flow sensor to determine if it's good or not. I'm trying to troubleshoot a rough idling problem which arose today.

I was wondering if anyone knew the readings I should get if I check the connections. I've already used the connector cleaner on the wire (assuming that this is the anode type setup on the inside of the MAF) and the connections so I don't think it's a matter of the system being dirty. Before I invest in a new one, I just wanted to make sure that this is the problem.

If anyone knows, the help would be greatly appreciated. Thanks.

did you try the idle valve?

Thanks Anil, but I not looking to go there until I check the air flow properly first. When I unplug the jack that goes into the MAF, the idling returns to normal. I'm assuming that this is the problem. Frustrating like hell...

I meant cleaning it

try another MAF and see if it clears up.

best thing to do here.


i had a problem with mine, thought was the MAF, and got one borrowed and tried it, same problem, wasnt the MAF (almost bought a new one).

Thanks brothers It wasn't what I thought. The timing was slightly off. The car is back to it's usual deceptively quiet self. Thanks for the help. Peace.

LevinBZR, any cause for the timing to come off?

did you run a scan?
