    Welcome to Allpar. Is it a low or rough idle or is it engine vibration being transferred into the car body?
    Does the noise change when steering left or right at low (i.e.-parking lot) speeds? Does the noise change between Drive and Reverse?
    Were the motor mounts adjusted after installation to equalize axle lengths? Usually, but not always you can use the bolt washer marks left behind to place the mounts in their original positions. Any shiny metal spots (witness marks) on the old mounts that might indicate a metal-to-metal contact?
    Were OEM mounts used?

    There are 2 engine mounts and 2 torque struts on the engine. One engine mount on driver's side engine compartment holds transmission to body. The passenger side engine mount holds the engine bracket to the body. To get to this you have to remove the upper and lower torque strut on the passenger side, remove the front wheel, use a T55 torx bit to unbolt the engine bracket from the mount. Then you remove the power steering pump and jack the engine up so you can remove the bolts from the bracket. Then you can access the bolts on the passenger side engine mount. Is this a basic outline of what you did? It would be easy to confuse the upper torque strut as an engine mount and think that is all that holds the engine on the passenger side.

    Two things that fixed the poor idle in gear. I took the throttle body off and cleaned it with a fiber brush and cleaner. Second problem was a cracked hose on the charcoal canister. The hose has curves and a small end and large end. The hose is not available. My fix. I slid heat shrink tubing over the hose and heated it until it conformed to the hose shape. Slid a second layer over and heated again. Harbor Freight has the tubing cheap.

    There is also an idle adjusting screw at the cable crank on the throttle body. I have not adjust this. The hose and cleaning seems to have worked and the engine does not drop in rpm's while in gear or turning on electric power or a.c.
