I just replaced the plugs a couple months ago but when iI get a chance I will pull the plugs out and take a couple pictures. FYI the afm was already removed when I bought it and it has 224,00 miles on it if that helps any.
This is what I pulled from my scan tool but dont fully understand it. Makes me think of injectors but dont want to throw parts at it for nothing. As far as exhaust, I dont see orhear anything there.
