My 97 Glastron with a 5.7L GL has developed a very rough idle, sometimes stalls. As soon as I hit 1000ish RPMs, runs like a top. Spark plugs were fouled out, so I replaced them. Was better for a few runs but doing it again. Cap, rotor, plug wires have all been changed in the past 2 years. Holey 2 barrel carb has been rebuilt a year ago. Fuel/Air mixture adjustment has been tweaked and didn’t help. The Choke plate is open and not stuck. Someone mentioned replacing the Idle Air Control Valve (IAC). Any thoughts?
