I have a 2016 RDX Tech with 60K miles on it. I've noticed the tach needle jumping around a little on moderate acceleration (this does not feel like the transmission shudder issue). Gas mileage seems to be unaffected (22MPG around town, low 30s on the highway). I use mid-grade or premium gas, and a bottle of Techron every 6K miles. Engine air filter has always been changed at 10K or less miles. No idiot lights on or stored diagnostic codes. Where would you start diagnosing this? Plugs? Coils? Fuel pump or filter?
Thanks in advance for your replies.

 

i'd start by popping off the plugs and taking a look at their condition

 

I would think its the Torque Converter just being finicky, which seems to be common on these cars. Mine does it sometimes but I don't really notice...
