I am throwing all types of codes p0171, p0174. After I removed and plugged vacuum lines going to sensors on EGR it threw a p0106. Smoke tested intake manifold resulted in EGR leak placed in a block off plate to see if it helps threw p0108 and p0109. I know there is sensors on top of the EGR that measures exhaust and intake gasses. I am trying to throw as many related codes as possible to determine faulty EGR. I was wondering if my solution of a brand new $180.00 EGR is it MAF was replaced.
