5.7 LOW ROUGH IDLE

Sent to Car Experts May 22, 2005 6:47 a.m.

800 MILES AGO I INSTALLED A REBUILT 5.7L IN MY 1995 SUBURBAN 1500. SINCE THEN I'VE HAD A LOW ROUGH IDLE, AROUND 500-600 RPM. RECENT INSPECTION OF THE SPARK PLUGS SHOWS CYL 3 & 5 ARE BURNING LEAN. NO VAC LEAKS FOUND.

HERE'S WHAT I'VE DONE, 2 SETS OF PLUGS, CAP, ROTOR, WIRES, NEW INJECTOR FOR THE BANK RUNNING LEAN, NEW CAT CON, NEW KNOCK SENSOR, NEW HARMONIC BALANCER (the old one has wobbling).
