VERY useful!

I've only just used the OBDLink Android app during my lunch break, and I have a distinct path to follow now.

P2004 IMRC stuck open.

Doing some searches around here and the internet in general, this seems a very common problem that crops up shortly after installing a stealth CAI modification.

So when I get home this evening I'll check the IMRC according to my Ford Workshop Manual - Powertrain Control/Emissions Diagnosis 2004:On Board Diagnostics, Section 4, sub-sections HU15 thru HU41, IMRC troubleshooting steps.
