Rough Idle Question

912 Views 2 Replies 3 Participants Last post by  cgmike10
Any idea why my 430 idles rough? I'm out of warranty and want to ask on here so I don't have to drop silly money at the dealer. Thanks in advance for any help.

RE: Idle

When was your last oil change ? If it's rough and you can hear a little knocking sound, then you need to add or replace oil asap.
check your engine mounts

Common problem....check your engine can do this by putting the car in drive and stepping on the brake and gas. If the engine flys up with no visible restraint on one, or both sides, you need new engine mounts.
