Thanks for the How stuff works... actually appreciated it!

A friend of mine suspects that its my timing belt (which was mentioned in your link)... Im not really a mechanic so I just want it fix and the assurance that my car is reliable.

I do have to admit I have a heavy foot but my car is matic so it should not matter...

Nag ka mild stroke kotse ko (in my own layman's thoughts, will also give you an idea my age) and I guess it affected the valves...

Ang alam ko:
1. car was still normal even when the warning light was on
2. car went straight to casa, no other side trip
3. Oil Level is normal
4. No Overheat

Will give them time to isolate the problem... I just want to arm myself with some knowledge :-)

Thanks for all your inputs!
