So I just got out of training and back home for a couple weeks from the military and my car has been sitting for approx 6 months. i started it and it threw a bunch of codes. i limped it down to my shop and cleared most of them but i still have 3 codes stuck in there that i cant clear. trottle actuator electrical malfunction (P1558), throttle actuator adaptaion not started (P1579), and throttle valve controller malfunction (P1545). i tried running adaptation but it wont do it. my car is in limp mode and wont rev about 1500 rpm and is constantly misfiring. none of the techs or dealerships ive talked to have heard of anything like this and i dont exactly have 1000 dollars laying around to try and throw parts at it. if anyone has had or heard of anything like this please please post. ill try anything. i havent driven my baby in 6 months and would really love to be able to. anything helps. thank you.

 

all 3 of those codes sound like they are coming from the drive by wire throttle controller. First guess would be to replace the controller.
