Alright, Im fixing my ignition coils this week. That is one of the few problems a 2kMax has (from my readings of this forum).

From the experience of other users of the forum, the MAF may fail someday and the cat seems to be a problem for many. Is there any other "common" problems with the 2k I should be aware of?

And how can I check my MAF and my cat? I would like to change it BEFORE it breaks on me in the middle of nowhere in a snowstorm.
