Air Flow problem on my '86

[limomanb]

Recently threw some codes and had a buddy of mine check it out while I was away. He said that the code read an air flow meter problem. Don't know much about this ...is this an easy job if I need to replace the air flow meter? What is a good price if I bring it in and have it done at my local shop?
I noticed a few times where the car would actually hesitate for a second or two...then the SES light would come on and stay on....car would run fine after that. Turn off..start it again and no light...
I have an '86 auto with 85K on it. Appreciate any help.

If, by "air flow meter", you mean the Mass Air Flow (MAF) sensor, it's a piece o' cake to replace; it's part of the intake ducting leading to the throttle body from the air cleaner.

Simply unplug the MAF sensor, then remove the MAF from the air cleaner box by unclipping the clips on either side of the MAF sensor, then loosen the clamp that holds the MAF sensor to the accordion-pleated intake hose. Installation is the reverse of removal.

I would hold off on replacing the sensor. It is expensive for what it is. Reasearch the problem a little more. Just exactly what engine code do you have. I have come across several times when the code indicated the MAF circuit or sensor, when in reality it was one of two relays. The price difference is huge, the relays cost 17.99 from mid-america. Find out what codes you have, and check back.

What is the typical price for the MAF sensor? I may just replace it and the relays. I don't know what the previous owner had done to the vehicle...I feel better about changing both.

By the way...it's code 36.

In Mid-America the Heavy duty high performance MAF is 229.99 and the AC Delco Maf is 319.99.

The Code 36 is Mass Air Flow or Mass Air Flow burn-off Circuit.

Do you have anybody with an 85-86-87 vette. If you do you can put there MAF on your car and see if the codes are still there. When you put it on remove the negative terminal of the battery to clear the already stored code. If the light comes on again then you know it is not the sensor. However if it were me I would by the relays from Mid-America for 17.99 and do that first. Chances are really good that the problem would be fixed. They are behind the battery and take not time at all to swap. Then if that isn't the problem get the sensor, after all they recommend you buy the relays if you buy the sensor.
