I got a recent recall notice also......for my '06 4-banger. I've not acted on it yet but to see what this forum had to say. I passed NJ State emissions at a state facility last year with no problems, so do you think I'm fine letting it go? I hate the idea of going to the dealer if I don't have to. It'll take longer than the "about one hour" the notice estimates I'm sure and I wonder what they'll scratch, ding or snap off when they do the job.I got one also, and have yet to take it in. I did talk to the dealership and all they said they had to do was reflash the ECU, and it should only take about and hour. Something about making the operation field of a sensor wider, other than that I’m not too sure. Maybe it is to compensate for the 10% of e85 they are mixing with gas? Because with the e85 I have noticed a significant drop in my mpg’s on my 64 mile daily commute.
