Its probably the original maf. No my car doesnt seem to have any trouble accelerating. That tool you bought, will it reset cel and give you trouble codes? Heres the one I was looking at...

Is this something like you have? Im still not sure if Im dealing with a MAF or bad 02's. I just called the shop and they want 150.00 to scan for codes.
I just looked up the pocket scanner you wrote about. When it gives you a code what do you use for a reference from that point? Is there a book or something with it?
