I did clean it. I think it is responsible for my check engine light. Anyways you say upgrade I need Flash. I am not sure but I think you mean I need to change the chip. !st of al where can I get an upgraded maf and how will this benefit me? @nd where is a good place for the chip and is it worth it?
First off, what year is your car? The 96-97s have a 70mm MAF and that would be a good upgrade for earlier year cars. I'm not 100% sure on this, but I think you need a chip or a tune that Justin mentioned to get it to work. Check the junkyards and see what you can find.
