Odd Vibration at different RPMs

Hello.

I had picked up my son from school and had checked the mail when I got home. I live on a dirt road and live at the end. I turned into my drive way and thought my son would like it if i revved it to 5K in first gear and rooster tail some dirt from the front tires. He did, but now I have a problem.

At 1K RPM idle there is a vibration with engine RPM in neutral and it does down until 2K and its louder there than at 1K. It also has the vibration when driving in the same RMP ranges. Have I possibly burned up (or made out of balance) a pressure plate or the clutch disc? It does not slip or make any crazy noises. The vibration is strong enough to rattle the interior of the car. I have bought a new clutch system but I do not want to rush into changing something that may not be required.

Here is my setup.

I just replaced the LCAs with energy bushings.
CV Axles are New.
I checked the engine timing and it is correct. (timing cover cam bar and timing pin for DOHC 2.0L Zetec)
I replaced all the engine and transmission mounts about 1 month ago.
Transmission lower mount (torque mount) has energy bushings installed
I ordered NKG IR spark Plugs and wires to replace the current ones which are about a year old.

Is there anything you could think of that may make this vibration. any information would be helpful.

Thanks in advance.

Was the Check Engine Light (CEL) on before/after your rally outing? If it was on prior to the incident, I'd scan for new codes.

You mention having the timing checked, but did they replace the timing belt, or has it been replaced somewhat recently?
Are there any new noises coming from the engine itself?

It's also possible you may have hit something like an O2 sensor etc with one of the rocks you undoubtedly kicked up.

Maybe the passenger side engine mount went out, I would check it even though it was new.

To DarwinSays:

The check engine light was not on before nor after my rally outing, :-) However when I can get back to it i will place it on a code reader and check for codes. I am sure that there are codes that do not activate the CEL.

I checked the timing myself using the tools mentioned in the previous post and the belt is about 3 months or 3000-4000 miles old. I checked for looseness and missing teeth on the belt be removing the top timing cover and turning the engine with the 18mm on the crankshaft.

I will check the lower o2 sensor for damage.

To forddorf:

How do you check engine/transmission mounts? I had a bad ball joint I did not discover until recently and I had replaced the top engine and transmission mounts trying to correct the noise I was hearing. I still have the old mounts for troubleshooting purposes. I will let you guys know what I find, if anything.

It is probably the passenger engine mount. That mount is a hydraulic mount and when the hydraulic chamber fails the engine rattle in the cabin is horrendous. And the Anchor mounts are very bad at failing.

What brand mounts do you recommend getting for the focus. I can only usually find anchor and I do not really want to pay for Motorcraft mounts. Since i just got them a bit ago they should be under warranty.

If you want to deal w/ changing them out then get the cheap anchors.

What I am asking is... Is there another brand that is not anchor or motorcraft. I can find several brands of clutches and control arms and several brands of many different things but no real brands of motor mounts. Are their other mounts that are made by other manufactures that I am not aware of?

Only the motorcraft seem to last. You can get good prices from Village Ford, send VillageAndy a pm with your vin. On my 2007 SES all three mounts cost a total of $166.

Well if that is the case then that is fine. I just worry about replacing the mounts and it not being the problem. The vibration is not consistent through the rpm range, but I will explore this option and let you guys know. I will try to figure out how to do a search for VillageAndy and send him a message.
