Looking for suggestions…
I acquired a 1998 5.7L Suburban that has a remanufactured engine with 20,000 miles on it. An issue that I need help to get around is a rough idle and awful-smelling exhaust. There is no CEL illuminated. The exhaust sticks on your clothes similar to when you use a lawn mower for extensive periods. Not like raw gas. No loss of power. The timing is dead on.
I have replaced the following:
-Plugs
-Cap
-Rotor
-Wires
-Temp sending unit
-Cleaned throttle body
-New throttle position sensor
-New idle air control
-Upgraded spider with regulator
-New throttle body and upper intake gasket
I have access to a reader so I can get live data, I just don’t know what is within the normal range on certain things.
Thank you in advance.
