My 89 Vette started getting code 36's today. My MAF sensor is fairly new, and I replaced the burn off relays last summer. What am I missing? I tried resetting the ECM, by pulling the ECM's fuse. I still get the same code.
the maf code will go away if you disconnect the battery.
Then reconnect the battery and determine it is actually gone.
then start the car, wait for the check engine light to come on, and then shut it off, and recheck codes.
If it comes back, you need to check the maf connector, associated wires, and grounds.

Thanks for the quick reply! One more question. I took the MAF off, and noticed that it looked dirty inside. Most likely from the oil from the K n Air Filter. Can I use carn cleaner to clean it? Or, shoud I just leave it alone?

I don't know about carb cleaner. But I know that its fragile I probably used the wrong cleaners on the cars that had MAF sensors. I remember using denatured alcohol with success. Hopefully someone will recommend a known good solution.
I would absolutely read and print out the link that vader86 posted. You can purchase a can of CFC electrical cleaner at autozone to clean the MAF with.
I have been fighting this recently. Follow the flow chart and if you get all the way to "bad ecm or wiring" like I did, then get a can of contact cleaner and a small screwdriver and scrape on all the contacts of the MAF relays and MAF connector, and bend the pins slightly so they make better contact. This seems to have gotten rid of my problem.
The C4 cars are aging like the drivers The female part of a terminal connection relaxes over time and you tend to lose electrical connection. This is especially true when you deal in low voltages as is seen in auto sensors. I have been using a product called Oxi-Guard on sensor connections in recent years. This is available at Home Depot/Lowes and seems to maintain electrical contact when you have clean connections. It is found in the "electrical" section of the store.
