This is what i mean about the intake manifold being top removable. I cleaned my IACV a while back, and it solved my CEL and idle problems. But im not saying that it will work for you tho.





This where the EGR Valve sits, the ports usually get clogged over time.



This the inside of top half of Intake manifold, it was gunked and blacked out. This is after cleaning it. The IACV on behind the intake manifold top half, pictured below.
