Shuddering on slow down at highway speeds, not braking
just like the title says. I cant wrap my mind around it. Ill accelerate to 80mph and then just let off the gas, and my car will shake side to side a bit. It feels like the engine is wobbling. Dont know if its suspension related, brake rotors or something within the motor.
no codes, no misfires, no problems on acceleration whether light or WOT. steering feels a bit loose, which makes me think suspension, but trying to eliminate motor concerns. Running Cobb 2+, 91 pump, 78k miles, feel like i could do for a walnut blast, but thats just a hunch. n54-heads unite. Thanks

no brake issues other than the rotors feel worn, I ordered some as i needed to anyway. Just dont know if they are the actual source of the issue.
Wheel balance could be a player. Any thoughts if it could be motor?
