2003 Chevrolet Suburban 1500 LS 5.3L Poor Idle Quality
Came in with low rough idle and codes P0171 and P0174.
Found intake gasket leaking. Replaced intake gaskets and
injector o-rings. Fuel trim is now fine and idles smooth
but still low (500rpm). Customer complains that it's just
the same as it was.
