[quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous]Another question about my 2009 Ford Escape.

A few months ago on a trip of about 100 miles the engine seemed to run a little rough for about 5-10 seconds several times.  Then later that day on the way back the check engine light came on.  That was a Saturday.

On Monday I was going to take it to my mechanic after work to see what was up, even though it was running fine with the light on, but in the middle of the day the light went off so I didn't take it to the shop.

Do you think I should find out what the code was?  Or should I just be satisfied that the light has been off and it has been running fine for the last few months?[/quote]

My bet would be an O2 sensor.  I had a 2011 Escape Hybrid 2wd that would run like a top all day long just driving around town, but after a couple hours at highway speed, especially if I was really hauling ass, I’d get an engine light. It wouldn’t run any different, it would just have a code. So I’d check the code, and it was always the O2 sensor. But then it would clear itself within a day or two after going back to normal around town driving. If you have a code reader, see what code it’s throwing. If the running rough happens again, and corresponds to another light, check it right then while it’s still on, before it resets itself again. Ford ECUs are supposed to store codes, but mine didn’t. Go figure. Code readers are fairly inexpensive now, you can get a decent one for under $100 now. And knowing those codes can really help narrow down the diagnosis for what could be causing the running rough. Because it could be at least half a dozen things, and you don’t want to just start blindly fixing stuff without knowing the specifics. [/quote]

I don't have a code reader myself but my mechanic would check it for free.  I have actually driven it on a 2500 mile trip since then with no issues so maybe it's nothing to worry about?[/quote]

Most of the time, the amber/yellow check eng light is emissions related codes. The red lights are the scary lights, lol. [/quote]
