budshaw Posted July 14, 2015 Share Posted July 14, 2015 Lately I,ve been getting poorer gas mileage (approx. 17-20 mph) and blowing black smoke when I get on the pedal. Is there an adjustment on the TB or could there be other causes? thanks Link to comment Share on other sites More sharing options...

budshaw Posted July 14, 2015 Author Share Posted July 14, 2015 As soon as I posted I thought about the O2 sensor. I'm sure it's ancient (if it has one). I'm going to look now. Thanks for heads up. Link to comment Share on other sites More sharing options...
