Can't believe I just read 9 pages
anyways, it was stated earlier (sorta). The only thing that fixed my sputter was programming it to idle higher (raise the a/c idle speed too).
I still see the rpm fluctuate, but the vibrations and rough idle feelings are 100% gone!
While speaking to the tech about this, I mentioned if we are only masking the symptoms. I liked his response though: we've done everything else and this issue isn't harming or doing any damage; it's just rpm play. so if raising the idle speed helps, why not do it?
