Has your engine check light came on, with some codes, and you either: erased the codes/shut off the light with a Code Reader, or erased the codes/shut off the light by removing a battery terminal cable for a few minutes? I've hear from some folks who have left their engine check light on and drove around with it on for weeks-to-months. Didn't do a thing about the codes that showed up, until they could afford it. Just what happens if you have a Code Reader, you go ahead and erase the codes, which will also shut of the engine check light and decide to wait to see if the engine check light comes back on? As for me, I don't like driving around with the engine check light on, let alone not being able to get an appointment, for at least a couple of weeks, to have it all checked out. Thoughts about this?
