For future instances that your CEL comes on, don't just reset it and think you've magically fixed the problem. You have been provided the proper procedure for ascertaining what exactly your ECU is saying is wrong via the CEL flash count. Find out what the problem is so it can be properly addressed. GAH!

AND, your car is a '98; therefore, it has 2 O2 sensors.
