Default Code 36-I'm Open To Suggestions

I get the old "Service Engine" light a lot and clear it through the negative battery cable disconnect, but this week I had a guy hook up a code reading unit and it said "36". What do you guys think I should try first? Thanks

Replace the Mass Flow Burn-Off relay located behind the battery. It's the relay farthest from the fender well.

65Z01, is that an automatic change? It could not be anything else like a loose connection under the MAF, wire connection, relay connection? If I replace it then I won't have the code 36 again? Thanks.

First step is to replace the relays behind the battery on the firewall.
Replace both, the code clears when you disconnect the battery for a few minutes, and it should not come back.

Together they are about $20.

If the code returns, its likely either the actual MAF or wiring.
