Car running strange lately
Lately my car has been running a bit strange.
The upshifts from 1-2, 2-3 under light throttle in the 2000-3000 RPM range are a little jerky. Feels more like a thump. This happens also in 4th gear as well. The downshifts are also a bit slow and jerky. Car is AT 335i with 88,000. My car has never acted this way before.
Another thing I noticed is that in the mornings, the RPMs used to spike to warm up the engine but that no longer happens.
This strange behavior occurred after I reset the ECU, throttle adaptation, and transmission adaptation with my Bavarian technic cable. At first after resetting the throttle adaptation, the RPMs started surging therefore I had to clear the codes. I read that this surging is common after resetting the throttle adaptation. I've also read on this forum that some members weren't happy with the results after resetting certain adaptations. Is there a way to fix this issue. Does my car need to be re flashed or reprogrammed? There's no codes on the dash or when I scan it with the BT cable.
