2004 Chevrolet Suburban 1500 LS 5.3L Low Power
This one is though. Very low power when accelerating. Has low exhaust pressure and low engine vacuum 14in at idle even lower at cruse. Calculated engine torque is 4% at idle. It is not exhaust. I have removed and still same thing. No codes. Fuel pressure good....
