Engine Performance problem
2000 Mazda Protege 4 cyl Front Wheel Drive Automatic 111000 miles
I have owned my 2000 Mazda for about 18 months and shortly after buying it the check engine light came on. Long story short, I had both converters replaced, both O2 sensors, new spark plugs, and new coil pack. It was only after the new coil pack did the problem get solved - or so I thought. A few months ago the CEL came back on. I was told that one of the 02 sensors had failed (b/c I went with a cheap brand) and it was replaced with a Bosch. This did not solve the problem and the CEL would come on for a few days and off for a few days. The CEL has been on non-stop over the last couple weeks. Up until today, the car drove great. However, the idling became rough today and actually stalled out twice while waiting at a stop light. The car (when not idling) drives very nice. I have spent enough money on this car already and am at my breaking point!
