stuttering on hard acceleration
OK so I have a 2005 c230k ss with the m271 automatic and I like to drive my car rather hard and for the second time I've gunned it at a red light and it'll go hard then reach about 4-5k rpm in first, stutter, then the check engine light comes on. Then my engine is shaking a little more than usual so I turn my car on and off then it runs fine but the light is still on. The first time it happened I changed spark plugs and reset the light and it was good but now I'm stumped anyone got any idea of what could be wrong

Get hold of an OBDII scanner & see what codes are being stored.
Either fuel starvation or ignition breakdown likely.
Check fuel pressure at the Schrader valve on the front fuel rail. s/b >3.8bar or 55psi while cranking. When last did the car have a fuel filter.
OBDII readings will tell you if you have a bad coil etc.

P0128 = Need a new thermostat ~ car is running too cold
PO171 = System too Lean (Bank 1)
PO304 = Cylinder 4 Misfire Detected
While you might have a MAF problem, next thing to check is fuel pressure. Fuel trim is too lean. She is starving of fuel.
Replace the thermostat.
Check plug & coilpack for cylinder 4.
