1991 Chevrolet S10 2.8L Excessive Emissions, Poor Idle Quality, Poor Fuel Economy
Posting for another shop so I don't have all of the data available. Runs rich at idle with 14" of vacuum. Engine temp was 150, replaced thermostat. Still rich. Smoked the engine block and got smoke out of the throttle body. Replaced the intake manifold gaskets...
