Have a 92 Civic Vx HB that stall when you push the clutch in when the AC is on. Doesn't do it when its of. Check idle boost, new IAC, base idle, plugs, coil, valve adjust, compression test, PCM, ground circuits, injectors serviced, check specs on throttle pos., TW, IAT, fuel pressure and flow, O2 is running high, EVAP, AC pressures ok. Still can't find the problem. Any help at all is appreciated.
