    Hello All:

    I just got back from getting my LeBaron emissions tested (3.0V6), and
    it almost failed idle hydrocarbon. Here are the results:
    Hydrocarbon Loaded: 82, alllowable standard 220
    Hydrocarbon Idle: 217, allowable standard 220

    I almost failed IDLE Hydrocarbon.

    I went back and looked at least year's test, and the Idle Hydrocarbon
    was 145. So, sonething has changed in one year (and 8K miles).

    Any comments, or advice is appreciated. Thanks, and take care, Bill

    Most common reasons are a poor oxygen sensor, catalytic converter or just
    plain dirty engine oil.
