@#$%^&* Code 55 yet again
My recurring code 55 has reared it'* ugly head once more, only this time the light has stayed on steady for the entire trip.
EGR has been replaced several times until I found a good one on the shelf at Advance that would pass the bench test. Once replaced, it ran great for a few weeks. Then it started coming back. Cleaned furiously and lubed each time with different oils (turbo oil, lithium grease, 3 in 1, and lastly TriFlow with teflon). It worked well for the past several weeks, but haven't been doing much long haul driving due to some family issues.
Back on the road today and I'll be da@#$% if it didn't come back with a vengence. Stopped at a rest area and cleaned and lubed as best I could with out removing ..... nothing.
Has anyone ever had a digital EGR heat fail? Maybe a flaky PCM driver? Any other thoughts?
