So ive got an amazing 2011 LCI 328i. Ive done so much to the car to make sure id never have to do anything again. I maintain the car to the best of my ability.
I bought the car at 90k miles. Had almost everything you see on the build list done at around 120k or before.
I just had my mechanic do a valve cover change on the car. I used the oem cover and gaskets.
After putting it back together everything ran fine. Drove it for about 10 min then had a misfire on 4. Swapped to 1. We swapped coils, idled fine. No codes. We went to start it again and he noticed that the intake hose to the throttle body was disconnected the whole time. Like barely hanging on. This was probabky like this for a long time before he did the VC job. He connected it properly and I started the car. Instant Limp mode after idle. Then idles really rough and really wants to die.
I get these codes.
We disconnected it and it still ran like shit. Connected it again and it runs like shit. Left it barely hanging on, runs like shit. Limp mode instantly every time. What could be my issue? We only changed the cover.
I also did the relearn process thru the pedal.
