It is very possible that the CPI is the problem. It doesn't make sense that it would only foul one bank of plugs. Another thing that can cause the idle problem is the EGR valve, they had a bad problem with plugging up, and we had to change lots of them at the dealer. I can't remember if they came out with an updated part or if we just used the same ones to replace them. If you know someone with a scanner, have them check the EGR position, it may not be closing all the way. Just a thought.
