engine oil pressure
 

I had a warning that said engine oil pressure too low turn the engine off, and I stopped the car and check the oil level and it was fine. the engine was acting funny when I turned the car back on the revolutions were all of way to the top and the check engine light came on, what could it be?

Interesting. If you can go by the auto parts store and get the engine light scanned and get the code or codes I could help you better.
