What did you do today to your 3/S?
Very noticeable on the 2.4 with solid mounts. 2.0 should be less. I also have a monster side exit exhaust that adds some vibration. And big kelford cams. It all adds up to some vibes, shakes and rattles unless you are wide open. Then it all makes sense and everything is right in the world:)
Stock cams and full exhaust, it vibrated and rattled but seemed much tamer. Could be perception.
2.4 with balance shafts...purred.

Assuming you were able to get them to match stock cam gears within a degree or less does not mean your cams are where they are intended to be if you have done any of the following: different cams, resurface block, resurface head, different HG.
Adjustable cam gears are first and foremost to set the cams to where the manufacturer intended (OEM or cam card of aftermarket) and second to adjust the opening/closing timing and overlap to suit your mods and desired powerband.
This is accomplished with a piston stop, degree wheel, dial indicator and solid lifter. Takes a little time but worth it. Especially on a DOHC V engine with two sets of cams.

Should be good.....So why not run stock cam gears?
