1990 accord exr 5spd, 240,000km while accelerating or cruising, the motor will loose all power and shut down for a second or two, then come right back and drive fine. I have already changed the Ignition switch, distributor, main relay, new plugs, wires, cap and rotor. I've noticed the idle is high too, around 1000 rpms. What are your thoughts on Igniter, coil, pcv valve or fuel filter? could one of these be causing my problem? Thanks
