I have a 2004 Cl 500 and every time I accelerate the engine stutters and loses power and it does this at all the gears until I reach the cruising speed or I put my foot down on the accelerator
I recently changed the spark plugs, MAF sensor and the problem still didn’t go away
I dont have any check engine light or any codes

You getting good flow through your exhaust? Ignition coils good? Plug wires good?

how do I check the exhaust flow?

thermal imaging is the best way - it's what my mechanic does.
