2005 Dodge Neon rough idle in drive

[97prizm]

Hi all,
I just changed the plugs and wires which seems to help alot but with my foot on the brake and the car in D i notice a slight vibration at idle. Now it seems more pronounced after the car has warmed up but it isn't so bad it sets off the check engine light. I have always owned manual transmission vehicles up till this point. Is this a Dodge thing or is it time for an ATF drain and fill. It has the 2 liter engine.

Bad motor mounts.

And if you replace them, aftermarket motor mounts are absolute trash. Gotta spend the money on OEM mounts.

Among other things, check the motor mounts.
And I'm sure others will chime in with a ton of things to check/change under the hood.

+1 As a test, if you park up hill and down hill apply the parking brake and then shift into park before releasing the foot-brake and see if it makes it worse. If it does it's probably the engine mounts. Also get OEM mounts if you need them.

There's 4 engine mounts and they all last about 10,000 miles each. I've never been in one (even when they were new) that didn't need engine mounts.

The one that goes to the fender will require the timing cover to come off, iirc
