Car shakes on rapid acceleration
I have a few problems with my 328i 2011. On cold start it turns on then off and then I am able to start it after 2-3 starts, this doesn't happen anytime besides the morning. When I turn it on the car has a weird idle, it isn't terrible but it goes up and down rpms, not much like up to 1200, back to 1000, that area. When pressing the gas it feels inconsistent and when I rapidly accelerate to around 2500-3000 rpms the car shakes and when I get past to around 4000 it stops. Previous owner noted lower voltage on MAF sensor and Valvetronic motor. To me it sounds like a MAF sensor issue, but I'm not entirely sure as I haven't really worked on these cars much and I'm new. This could be a wiring issue as well, but I'd like opinions.

You could theoretically unplug the MAF on your first cold start and the car will just run on its default strategy. That would eliminate the MAF as the root cause of the issue. |
