There are no eml codes or warn lights on, but have also noticed that the engine sounds a bit rough/vibration if I rev it in neutral between 2000 -2500 rpm. Not sure if the two are linked. I have started with some simple fixes checking for vacuum air leaks (none found), changed spark plugs and a full set of new coil packs, but none have made the slightest change to the symptoms. Has anyone experienced the same and found the cause?

back in 2006 there was a mod to fix a loose throttle housing plug .
if you try to wiggle the black plastic plug it should be very firm ...
