MIL has been off and on for about 3 tanks of gas. Recently pulled code is P0406. TSB #1802707/TSB Item #10021686 summary refers to EGR valve, but have not accessed complete TSB document. I need a new EGR valve? If so, I need to pull intake manifold which involves pulling crossbrace at rear of engine bay to replace EGR valve? Chilton's not much help due to too little detail.
