This morning, when I went out to start the caR, I received the "Reduced Engine Performance" message. This seemed strange since I've not had any problems recently (outside of 06/07 GT Valve Body issues). I turned the caR off and immediately restarted it. No message. Drove where I needed to go (short local drive). Drove it home a few hours later. Had a longer drive planned for the evening, so I hooked up the VIDA to see what caused the message. The only stored code I got was "ECM-925D - Throttle Valve - Signal Too Low". I've not experienced any kind of goofy throttle related issues, so it's a bit weird that this would show up out of nowhere. When I read the codes, VIDA showed <30% error active, but said it reported the code because there were at some point >60% error. The only time since I've had this caR that I had anything I could have attributed to the TB was in July 2013 when I had some idling issues. At the time I did not have VIDA, so I just blanket replaced all the things that could have been involved and could use replaced anyways (BPS, FPS, MAF, Plugs, Coils, Air Filter, PCV System, ECU Relay, and had the Throttle Body cleaned). Somewhere in all of this, my problem went away and I was happy knowing my caR was that much closer to Stage 0. At the time I always sort of had in my mind that it might be a throttle body issue (don't remember why now) which is why I included the cleaning. I'm wondering now if I didn't just delay the eventual failure of the unit.
I searched and searched and cannot find anyone who says they had this code. Has anyone had this and if so, what did you do? Also, I'm assuming this may end up with needing the throttle body replaced. I think I've read someone was able to do this without removing the intake manifold. Anyone have tips on this? If I have to do it, I'd prefer to get away without having to do as much work as vLGrok did in his famous post (http://forums.swedespeed.com/showthread.php?176501).
Thanks in advance for the advice.
