Trouble Codes: P0129/P2172/P061A
Well, after nearly two years of trouble code-free driving, it happened today in triplicate: (definitions from Predator trouble codes)
1) P0129 = barometric pressure too low
2) P2172 = throttle actuator
3) P061A = unknown
I had just started the car after it sat for about 1/2 hour, backed out of a parking space, and proceeded through the parking lot when the throttle response died and the engine stalled. Upon restart the check engine light, the Electronic Throttle Control (ETC) Light [the red one next to the CEL that looks like two backward parentheses with a lightning bolt between], and the BAS/ESP Light were on. The ETC was flashing, which according to the owner's manual means something needs immediate service. The car ran in a limp mode: performance down (I didn't really push it!), tranny shifting was strange, and it never went into overdrive or MDS.
Upon arriving at home I pulled the codes from the EVIC and with the Predator. I tried pulling Fuse 11. Upon restart the idiot lights were out, the engine seemed to run okay, then the idle got rough and it stalled, and the idiot ligths came back.
I then installed the stock tune from the Predator. No difference.
And while trying to keep the idle up by using the throtte, the engine stalled and another code popped up: P2174 = sudden low air flow.
I did a search and found only (1) occurence of P2172 more than a year ago. The guy indicated the stealership said something about throttle cleaning. He never reported back after it got fixed.
So, does anybody have any real life experiences with these codes?
All input appreciated before I take it in to a stealership.
