Just switched my tired Lodge plugs for some NGK's (BP7ES) on my CA 2L. Running warmed up and driving it settles back to about 1500 RPM at a stop, then takes a minute or two to settle down to appropriate idle speed. Is this a dwell re-set issue, or?

what was it doing before the plug change...

running on 3 cylinders, checked the plugs and one was cracked. car runs great now minus the idle issue noted.

idle elevation

Look for a disrupted vacuum supply line used at idle or at normale running or a return spring on your accel linkage either of which could have been disrupted while in service repair.
