    I ran through some high water saturday. Truck started to miss like the plug wires got wet.
    I have replaced wires,cap,rotor,plugs,fuel filter. Still running sluggish/surging when under a load. At idle and wide open it runs good. Its showing codes for both O2 sensors. Can o2 sensors cause this kind of problem? Any other ideas on what to look for?
    thx

    Maybe you sucked some water into the exhaust side of your head/heads, maybe the catalytic, check your oil (don't laugh , I've seen it happen) for water, if it was as deep as it sounds coulda drowned all kinds of emissions shit.

    It was on a flooded spot in low area on the highway, saw it at last minute. Hit at prolly 35-40mph after jamming the brakes on.
    I have checked the oil, no visible water. Checked the air cleaner to, no sign of water.

    Replaced the "upstream" O2 sensor and its back to running good. Never would have thought a bad O2 sensor would make it run that bad.
