P2122 and P0108
Hey, need some help.
Started the car today at work, and after a minute or two of very low speed driving through the parking lot, got three messages: Service Active Handling, Service Traction Control, and Reduced Power. Power was certainly reduced, though it still ran and could get up to speed, if slowly.
The P2122 is something wrong with the throttle position sensor stuff, typically the pedal or connector failing. P0108 is a problem with the MAF (MAP?).
My car is blown, A&A, and a few days earlier I had made a longer run at higher RPM, and when I got home, it dumped some oil on the ground. I looked all over but couldn't figure where the oil came from, though I'm betting it was blowby. If some of that oil got on the MAF, it would throw the P0108 code (ask me how I know). Could oil up the snout also cause the P2122 code? Any throttle position sensor stuff in there?
Note, that was like 3-4 days ago, and the car has driven just fine since, so it would seem kind of strange to have it be a problem much later. Just checking ideas before replacing the pedal.
And what do you clean the MAF with? WD40? Soft rag?
Thoughts welcome.

And, more of the story.
I went back out a couple hours later, had the hood up to let it cool. Wiggled lots of wires, and wiggled the gas pedal. Climbed in, fired it up, no problem. No messages, no nothing. Revved just fine. Hmmm.
Shut it down, and decided to work on the hood. I had adjusted the hood the night before. It's an ACS, and the painters had set it back a ways, leaving a gap up front that was actually wide enough to let air in. I didn't want that, so I tried to adjust it myself last night. I ended up with the nose of it pushed down, which closed the opening, but then it wasn't lined up correctly with tne nose of the car. But I left it there for the day. As I'm looking under it, I note that now there are a couple of tiny wear points in the paint, where the hood was hitting the engine! Can't have that. So, I worked on it some more, and ended up back to proper height on the nose, with the gap cut in maybe half.
THEN I shut the hood, fired it up, and took it for a short drive, a mile or so. No problem at all. Hmmm.
I may go ahead and replace the throttle pedal assembly, just in case. Seems to be a regular enough problem from what I have read on here. Don't want to have an intermittent problem that lingers.
So I dunno.
We'll see.

IF I remember correctly, the problem just went away. But LOTS of folks on here have replaced the throttle pedal and gotten good results. If your beast is blown, be careful about pushing oil through the intake, that will screw it up in a hurry as well.What I got.

Oil in the intake
I have a 2013 Grand Sport. A buddy & I installed a catch can on it. The catch can was catching a ton of oil in it. Dano523 was super helpful with feed back to get all the lines where they are supposed to be. It's squared away now & I'm pouring out ounces of oil every week that would have been dumped into my intake tract. It's not even a FI car & still was getting oil ingestion. I would definitely look into getting a catch can for it for 'peace of mind'. As well as checking off one of the gremlins trying to reek havac.
