    engine got wet, rough @ low rpm ?

    after a heavy rain last week and run through some deep pudddles I'm running rough at low rpm. It clears out when get over 2K rpm. It is worse with the a/c running. When it first started it would run rough if I left the pedal in the same position say at 2200 rpm then goose it to clear it out. Comes and goes. Clear at WOTor heavy acceleration.
    If we had a rotor & cap thats were I would look... it feels just like that. Any advice ?

    funny thing. my white car does that as well. while using my hptuners i found my right front o2 sensor was pegging completely rich. water is getting into the connector and shorting it out. when the o2 sensor pegs full rich, the PCM pulls all the fuel for that bank. this causes it to run rough until the fuel trims reset.

    i would start looking at the connections.

    I had my 02 sensors start acting up when I went through a deep puddle once and it did the same thing

    Had the same issue. Changed plugs/wires/ cleaned the coilpacks/connections and it went away...

    Still need to grease/clean/replace the 02s
