I have a 12 pro with 12 silber turbo I got it out today and it started to stumble like running out of fual and when it did my a/f gauge went way lean, I thought it could be my fual pump but I checked it while driving and it stayed a 58 psi, so that rules that out, I also had a check engine light come on, so I pulled the code and got 51-10 witch is throttle position sensor abnormal rate of change, first of what does that mean, is the sensor bad and need to be replaced, or is it just out of spec. also do you guys think that both problems are related. thanks it will be going into the dealer in the next couple days but would like to here your guys thoughs or if anybody else have had this issue thanks.
