It blows black smoke out the exhaust
Flooding. I can start it but it is way to rich. Is it a sensor problem? on 1995 Chevrolet S10
Check to see if your EGR valve is not stuck open with some carbon. Remove the valve and look to see if a piece of carbon is not stuck in the pintle or tip of the valve. I have repaired this problem on S-10 Blazers and Trucks a lot.
Thank You! Will try that.
