    the obdI code 36 is MAF Burn-off circuit. I first would clean the maf sensor wires with CRC MAF cleaner just spray alittle do not touch the small sensor wires. clean the air ducts and If a oiled air filter is used make sure that you did not oil it too much.

    if after resetting the computer/ecm the code comes back then it will be the maf relays.
