Last May was the first time I had seen the 'check engine' light in my ford 98 Contour. I noticed a decrease in power and an increase in gas milage - my O2 sensor had gone out, I thought. I had a diagnostic run, and that was indeed the case. I had it replaced and taken care of - the light never came back on again.
I was driving down IH-35 last week and the light came on again. I had been carefully watching my engine powerband and gas milage, and didn't notice and real change. However, I know that the check engine indicator is tied to emissions components more than anything. Today, the light went off, and hasnt' come back since. What could have been causing it?
