Hello, I'm new on here and not a mechanic by any sorts but can follow directions. I did a quick search on here and the web for MAP sensor install but nothing jumped out at me. I'm doing an HP Tuners stage 2 tune and I've got engine knock they can't get rid of. I've changed my plugs already and now RPM suggested to replace both my MAP sensors because of a code they found. I don't know where they are or if it's even something a regular guy can do? Can anyone steer me in the right direction?
