Engine misfires at idle, changed plugs, wires, distributor and rotor and used several products designed to help rough idle and poor mileage, but still misfires. At speed it runs fine. It only suffers at idle and especially when the ac is on.

1999 Honda CRV misfires

Engine misfiring can be caused by worn or fouled spark plugs, a weak spark (weak coil, bad spark plug wire), loss of compression, vacuum leaks, anything that causes an unusually lean fuel mixture (lean misfire), an EGR valve that is stuck open, dirty fuel injectors, low fuel pressure, or even bad fuel.
