I am wondering the same thing....is it throwing codes? Oxy sensor still intack? black smoke out the exhaust(richness)?



Carbed - no check engine light. Oxygen sensor is new, doesn't seem to be black smoke out the exhaust. The thing runs like a top, just gets crap mileage.

There is an ECU of sorts, so I would wonder about a check engine light, but it's never come on, even when you start the car. Not to mention, there is no check connector where you could jumper it to pull codes.
