Cranking on the Fugly .... I've got a funny vibe coming in around 2400-2600 RPM.
I suspect my:
1. Front motor mounts
2. My current "tune" in the ECM (Power Vision)...or ....
3. My drive belt is a wee bit on the loose side at 3/4" deflection (Manual says 9/16" max). That could possibly set off a certain vibe.
Motor mounts now re-torqued and done. Were perhaps 10% to 15% loose of torque spec.
Will play with the tune soon. Didn't have time for a test run.
Anyone have experience with a possible belt-induced vibe?
