Many thanks for your answer. It helped tremendously. I have been suspicious of an individual (I apologize for getting detailed, but to sum it up, it is per se a "fatal attraction", and this individual is "capable of anything" (scary individual, to be blunt).
I searched "catalytic converter symptoms" and came across a site that was very helpful. All causes for clogging were very practical and possible; however as my vehicle is a 1990, and when purchased, the car had 57,000 orig. Miles; I have owned the car for 2-1/2 years and the odometer now reads 101,000. It has been a very good running car. In the site mentioned above, I became concerning when I read "most originally equipped converters are designed for a service life of well beyond 100,000, so if converter has failed at low mileage, contamination may be the culprit".
My vehicle has been "messed with" on several occasions recently which has caused me great concern and worry, and when the converter went "haywire" a couple days ago, I wasn't surprised.
I went back to the site to read about ways to check for possible causes, after receiving your answer.
I apologize for being lengthy w/my message reply; and thanks again.
