hi. im new here. anyways, i have a zj w/ 4.0 it has 306xxx kms on the clock. my problem is that i feel a loud vibration during idle but when i give it gas it goes away. even though there is a vibration, the idle stayed normal at 500 rpm. it doesnt ump up and down. changed plugs, cap and rotor and wires. have a gut feeling of it being a bad motor mount but any input will help. thx.
