Hold up Hoss...
Don't "check" the tightness on the cables.. don't "look" at the cables.
If that puppy returns...dealer it and let them fight the good fight. If you decide to take this one on yourself.. get out the 8mm and pull the cables off, remove the bolts and boots, look over the cables with a microscope and clean them really well.
3-4 months of fighting this code has taught us what really causes it.
And the last thing I'm gonna do is let one of these codes kick my butt around the block, then up and down the street again.
