So am back at the war on trouble codes:
When checking your engine running codes do you first heat your vehicle up to operating temp, then check the codes? If you don't heat up the car first is it normal to see an ECT Code 21? And possibly 92 System Running Rich. Because isn't the car supposed to run rich until it gets up to temp, or do I have that backwards. What does the ECT do again to help bring the engine up to temp?
Thanks
One other quick question, had either some bad gas or a slight amount of water in the tank, it was low luckily so filled it up and ran some gas line antifreeze. As a sign that this is working, any idea what color smoke I would see. I have slight backfire issue and black smoke, too rich coming out my exhaust. But keeping in mind I still have only about 15 k on this new engine. Still working it out. But just really interested in the above two codes and whether I should be checking engine running codes with the engine up to temp first. Thanks!
