I have to almost all the time be so careful of how I put my foot on the gas to ensure a smooth acceleration

I HAVE regapped my spark plugs to .022 with NGKs but the problem still occurs

Any advice or thoughts?

Thanks guys
Have you pulled codes? Even if you don't show a cel there may be shadow codes logged in your system. I went through a similar experience; hesitation on acceleration, I changed plugs thinking that may have something to do with it, but I finally realized it was vanos related. Codes logged but not showing active cel.
Can you guide me through that process?
