169299 miles
Same Problem

I love my car, had it for a few months. First two months no engline light and then it all of a sudden winks at me. Cleaned EGR ports and lines (were really nasty). Took off egr valve sprayed 2 cans of carb cleaner, left over night then blew it out.. nice and clean. still engine light comes on even after taking off battery cables and reseting it that way.replaced egr valve and Replaced solenoid and reset.. still same problems (light comes on after 50-150 miles)

put damn racing fuel in 1 gallon, then filled it up with premium. Also added 1 can of seafoam in gas tank. Drove 400 miles light came on around 170 miles. The engine runs so much better, it feels like a nascar and I cant get my car inspected because of the code. As far as my dad and I can tell with water and inspection the hoses are not leaking and are all on and secure as well.

This is what it says when I take it to get inspected (past 3 times)
