Do you know what error codes are being logged now, when the check engine light comes on? With it running fine for a bit and then starting to run rough and throwing the CEL, it may be the O2 sensor.

That's tricky, unless you can drive around with a diagnostic scanner, so you can read the code before shutting it off. For the O2 sensor, a diagnostic scanner is the best way to verify if it is working correctly.

If the car throws a CEL, even though it goes away, the code is stored.
Get a scanner, and retrieve the stored code.
If there are too many codes stored, erase them. Retrieve the new code as soon as the light comes back.

I really like some of the British words for things...such as bonnet (for hood). I once put some items in a locker at a train station in Madrid. The instructions for using the locker were available (onscreen) in about 8-10 languages. Two of the language choices were 'American' and 'British'.

The code should be stored, even if the light is out. You can buy a cheap code scanner to use yourself for under $20 US.

dindy, I was trying to compliment, not offend. I REALLY DO prefer quite a few British usage words to American usage words, with bonnet being one of those words. In many ways, England and other Commonwealth Nations do a much better job of educating their populace than the U.S. does, including Commonwealth Nations who have another common language that is not English. The need for a menu on a locker to have an 'American' selection and a separate 'English' section just (IMO) shows a negative aspect of the far reaching effects of 'American culture' (a phrase I dislike re reference to the U.S. re the arrogance it carries...IMO all people in 'the Americas' are 'American' - from Tierra del Fuego to Cape Columbia in Nunavut, Canada (I actually saw a Nunavut license plate on a car in California a few years ago!)). I have yet to make it to your fair country (my closest being Pasteum -- 50 km SE of Salerno, Italy), but I hope to eventually make it to Malta. If I do, I certainly may see some wonderfully modded Yari as we seem to have a fair number of members living in Malta.
