Re: code 36
I don't recall where it is. The burn-off relay puts a high current through the hot-wire element on the Mass Air Flow sensor, for a second, to burn away any oil deposits that build up on the wire. I believe this happens just prior to starting.
Check the connections to the MAF sensor. The sockets can become sprung and fit loosely causing problems like this. I've personally experienced a code that translated to "MAF voltage high" that was caused by sprung terminals in the MAF connector.
You can use a small pick-probe or screwdriver to squeeze them shut a tad and improve the connection. A little light sanding with a rolled up piece of sandpaper would also help. I'd recommend doping it with dielectric grease once you get it all refurbished.
