    A fouled plug can indicate incomplete combustion. Did you check the ignition?

    A good mechanic can suggest some things to test, but I wouldn't be tempted to start replacing things just to see if it helps. Much cheaper to read the codes first.

    I think you're correct - I remember looking at a replacement Corolla for my previous Toyota (before I purchased The ChuggyPig) and my tame mechanic informed me when he scanned the reason for the CheckEngine light being on, 0420 came up, and his advice was new cat/conv ($800 just for parts) - his advice was "Tell him thanks, but No Thanks!" - (My two furry CellMates just looked at me with puzzled looks, wondering why I should want to get a new cat when there are two perfectly functioning feline specimens already in the house (…and they've each been fixed!) :whistle: - Wil

    That sounds more like wild guessing than "diagnosing".

    If one plug looks bad, replace the plugs first; they are relatively inexpensive.
    Next you need to hook up a code reader and see if any trouble codes are set.
