Engine Performance problem
2000 Chevy Suburban V8 Four Wheel Drive Automatic 60000 miles
2000 k2500 suburban with 6.0 L v-8 starts hard when hot. I have done these things to attempt to fix it. New main tank fuel pump, spark plugs and wires, coolant temp. Sensor, mass air flow sensor, ampient air temp sensor, fuel filter. In the last 6 months it has steadily gotten worse. Could it be a fuel leak in the upper intake manifold, because it acts like it is flooding out.
