I saw that suggestion and cleaned it up a bit when I swapped the sensor. My TB was replaced not too long ago as the original went on us, but it was fairly dirty. I drove the Terrain to work today and it was fine for me, I'm taking it again tomorrow.

Our 2010 Terrain 2.4l is now having the rough idle and stalling at idle issue. It's happened about 8 times over the past two weeks. we are at 117k miles and its never happened before. I replaced the rear camshaft position sensor last night. Hopefully that will do it and I won't need to do the front as that one looks like a huge pain. I've done actuators on my 09 colbalt a few years back but that car through a code and idled rough all the time.

No codes on the Terrain with these issues.

The intake is toward the front of your vehicle. The exhaust is toward the firewall.

Which one is intake and which one is exhaust?

What is the difference between to 2 camshaft position sensors? Is one for intake and one for exhaust?

No, no Flex Fuel on mine.

I would agree, probably does reset after x miles , either way, the light is off, and that makes me happy!

I suspect that the code clearing had less to do with the gas you used, and more to do with driving a certain number of miles. Some codes reset after a period of time/miles if the issue has been corrected.

Out of curiosity, do you have a flex-fuel engine?
