91 Cavalier misfire under 1500rpm
Working on a 1991 Cavalier w/ 2.8 V6.
Has a misfire under 1500 rpm at which point it appears to go away. Scan tool shows Lean/Lean/Lean until 1500 then flags back and forth Rich/Lean properly. No Check Engine light commanded, no codes present. The car has recently had: Head Gaskets, Intake gaskets, Heads rebuilt, new plugs, wires, coils, and ign. module. Injectors have been swapped with known good ones with no effect. All 6 cylinders 150psi on compression test. Any ideas?  Thanks in advance
