I went in for an oil change and mentioned to the technician that my MAP sensor had triggered my check engine light. I generally don't opt. in to recommended service but the technician specifically recommended I let them change my fuel filter and service the fuel system. I was hesitant as I wasn't sure at the last mileage I had serviced the fuel system and changed the filter. He agreed to look over the filter prior to me making a decision. He stood by his recommendation and I agreed to let them do the work. In conclusion my check engine light is off, it turns out that a clogged fuel line can cause this light to come on. When I realized the light was off I immediately called to thank the technician and he advised hopefully it will stay off but if it comes back on then I know it's an electronic issue. I always recommend express oil change for oil changes because they are quick. Now I'm more likely to go back for other work.
