Would you describe the condition as hesitation or light pinging followed by decrease in power?
Could be LPFP, or HPFL on its way out , maybe be a bad tank of gas.

I get slight shaking while cruising on low throttle. This happens for first 5 min of driving in the morning. Then goes away.

The car also shakes when stopped at a light for like 20sec then rpm's go up then drop and everything ok. Weird stuff.

Only codes i have is the lambda codes as I'm fully catless......
