From what I saw, the check engine light went on immediately with a code 51 when the vacuum line was kinked to the egr solenoid. That happened right at idle. After I fixed that issue, I drove it for a couple of days with no issue, then the check engine light came back on while on the highway again code 51. So, it appears the vacuum side triggers right away, but the EGR dump process takes some driving. At least that's what I think is happening. Hopefully, after the cleaning, it should take care of it for another 100k miles.
