#egr 2004 v6

  1. 1st-Gen
    I have an egr valve code (p1487 and p2227) my mechanic said to drive it around a little to see if it'll unstick, but today it started running rough. It's now throwing codes p0300 p0401 and code p0305. It also started ticking in the engine. Is it all egr valve related?
