I’ve done a little bit of research and I just need some ideas on what I should check first. The truck has already had the intake gaskets replaced and they are brand new. I should also add that the truck drives normally and just has the light on. Another thing to add is that when looking at the scanner, bank 1s fuel trim is 15.6 at idle and bank 2 is 13.3. When the truck is revved up to 2500 rpm and sitting there the trims lower down to 10 or 11 as well. That’s still high in my opinion and just want to know what I should check. The MAF on the truck has also already been replaced. If anyone has any ideas what I should look for or what I should check next that would be greatly appreciated.</p></blockquote><p></p>
