Check engine light on for 2 years?

Sadly, there is no Autozone here, although I will ask around to see if I can get someone to scan it for me.

Just spoke with a mechanic, he suggested that I change the Oil filter as sometimes they get clogged and oil bypasses.

If not, its a couple hundred dollar pump and most shops want to pull the engine to swap it :(

Thanks

If there is any more information or help you can tell me I would be very greatful.

I had asked you about a problem I had with my car and we checked for vacuum leaks and also checked the PCV valve and tube for leaks and the service engine light did go off but after driving it a little the light came back on. Now the idle is off. In park it idles to high and when in drive it idles to low and then it dies. In park it idles at 2 marks above the 1 mark and in drive its at 1 mark below the 1 mark. When you are driving it, it goes as high as 2 1/2 to 3 rpms when it changes gears. I hope you can help.
Thank you

My car has over 127,000 miles and the service engine light just came on.
