As the title says my new to me 86 bird has a bit of an issue with a code 36 trouble code. Ive reset the code several times to check and see if it was an intermittent problem and every time it comes back on the next start after being run for a little while. Once I came to the conclusion it was not an intermittent problem I ran through the troubleshooting chart in the factory manual for the car and everything checks out to be fine. This fact that the wiring/hardware (relays and stuff) is fine is confirmed by the fact that when I run the car for a while and shut if off you can see the sensing wire in the MAF glow for a short period of time also the fact that this is happening confirms that the ECM is running through the burn off routine as it should. Everything that I have done in the line of testing indicates to me that the burn off circuit is functioning properly yet I still have the code 36 coming back. According to the manual its time to replace the ECM but is this really where I stand? I guess what im really trying to ask is what conditions does the ECM look for to set a code 36? The manual is great for explaining what conditions set the other codes but it seems like for this one they just say its bad, the comp knows it is, fix it without much real of a explanation of how the ECM determines this.
