I've been trying to figure out the source of a vibration. 04 4 cyl., 5 spd Accord, 110,00 miles. The vibration isn't serious but noticeable, more annoying than anything. Typically the car will exhibit a slight vibration at 2300-2600 RPM usually under light accleration in all gears. Under full throttle it's not felt.

Is there a TSB for this? I think it's an engine mount. Let's rule out tire/wheel vibrations. I had the 105k performed and the mechanic said the engine was in great shape. I read about the engine mount vibe at idle on automatics.

Anyone else have this issue?

Thanks...

 

Swap your tires around to rule out tire/wheel balance issues.

If it's only under load, it could be the drive axles.

 

I'm not sure what the correct speed ranges are for each gear, but assuming they're ok I'd check the clutch as well.
