E93 S65 M3 car shakes first 5 min after cold start

[VR6GTI]

Hello everyone. Before I take it to the shop, I wanted to see if you guys know what DIY fix I should try first.

The problem:
My E93 M3 car shakes for the first 5 min after cold start. It stutters front to back, not left to right, during constant speed. I would shift into 2nd or 3rd and set the cruise control for anywhere from 20-30 mph and let the car go at constant speed and it would stutter. Everything in the dash looks fine. No bad idle. No warning lights.
After driving for 5 minutes, everything is super smooth.

Anyone have an idea what could be causing it?

Thanks all.
Joey

Hey Joey - if you're able to pull the codes first, I would recommend doing that before bringing it to the shop. The stored codes should give you a definitive answer as to what is going on and where to start troubleshooting. Best of luck!

I went to Pep Boys and they plugged into the OBDII port but did not find any codes. I guess it's a good thing but now I'm still unsure what could be causing the stuttering.
