Car is 2006 Manual 29k miles.


So I drove to school like normal and when I go to start it after the check engine light is on. I drove it home, it was running / driving normally. Engine sounded fine. (and yes the gas cap is on)


So, should I go to autozone to get the code read? Unplug the battery/reset the car to see if it goes away?

I am assuming this is just a failing sensor or something, anyone have any ideas on what it could be?

 

Yes
No... not before getting the code read.

 

Radiator light on dash comes on sometimes on high rpm after the engine cools and i start every thing is normal. What could be the problem?

 

I think the issue is that your "search" button is apparently broken!

Yeah, that thread is way overkill, but read the first two posts, your answer is actually in the 2nd post.

If you don't care about the science at all and just want the answer, then see this post. https://www.rx8club.com/showthread.p...05096#poststop

There are almost as many threads on this subject as there are about oil.
