Crazy vibration while idling in D or R

I've been troubleshooting this issue for a long time now and have come nowhere to fixing it. I've changed engine mounts and all suspension components except the front strut assemblies( car's in garage now on jacks and I'm finishing up the Bilstein HD's tomorrow morn). Done half shafts twice. I still get a little vibration at around 60 mph. Axles are reman's so they could be causing that. Tie rods, inner/outer are done. I haven't changed any steering column components yet like the u joints or upper column.

The vibration is everywhere; dash, seats, steering wheel especially when I turn it left to right . . . all the while when I'm idling. As soon as I start to drive or reverse it disappears.

It's gotta be something drive-line related, no?

Transfer case bushing?
Transmission mounts?
Differential mounts?

This has got me stumped.

I've got an occasional vibration too and my research only came up with cleaning the MAF, didn't do it yet because mine looked to be clean.

I cleaned the MAF too. Didn't change a thing. And it looked spotless. 170K miles now. First time the front struts have been done too. I couldn't believe they lasted so long.

Didn't someone have a similar issue caused by a bad torque converter?

Or maybe a harmonic balancer issue...they go occasionally.

I had posted something awhile back about both being a possible issue. Vibrations in my book mean something is loose. I'm not even sure where the harmonic balancer is (around the water pump?) . . . Maybe the Vibration damper (11231438995) otherwise known as the crankshaft pulley? It does cover my build date of 10/01.

On a side note : Mmmmm . . . I'm enjoying a Biere De Garde I brewed back in September aged on raspberries.

So it appears that the harmonic balancer is attached to the crankshaft pulley. Is this just rubber around steel? I would fain never pay for a new engine because of this. Maybe if it's removed the vibrations would increase. I couldn't imagine the labor involved. . . .

Check idle control valve, O2 sensors, fuel pump, fuel filter and intake boots for vacuum leaks. You have a rough idle off throttle where the engine is defaulting to a preset fuel map. Somewhere, it's not getting enough gas and you are bordering on a lean condition code. It's just over the horizon...

I wouldn't bother with the harmonic balancer, it's likely not the problem. I had this issue with both my old Passat and my current Expedition, the issue was one of the ones I told you above.

Fans good. Sam, fuel filter is newer. I'll test the others. 02 sensors have never been done. No vacuum leaks in any of the secondary air system, intake system, or crankcase ventilator system as all were just done not 1 week ago and this problem has been long standing. Fuel pump . . .don't know how to check that.

No cel's on the dash or anything through the peake reader except one of my accelerator pedal sensors has been bad for awhile.

Change O2 sensors, clean the MAF, clean the intake air temp sensor, replace IAT sensor o-ring, clean ICV, replace DISA o-ring.

That should fix your troubles.

So over the weekend is got this code p0014 and p0015 ..
i got the car inside and check every thing cause i did a VCG last week..every thing was OK..
i tested the solenoid and the 2 of them are working but the exault one was slow to click click.so i cleaned them out and the car run just perfect..the car sit inside all winter and the solenoid must got stuck..remember that the idle was running a bit high before i got the code..in my case here i didn't get the lost of power.the car was just poling fine..

I have started threads about this problem and replied to threads regarding this issue. I myself have replaced ever thing possible and mine still is a 3000 lb vibrator in cold weather... wait for the weather to warm up and it will go away, mine does this every winter..

Nobody has successfully fixed this issue and it is a known flaw with the XI's. I'm to the point of just wanted to sell mine then deal it it anymore..

Sorry wish I had an answer for you.

Cool.

Do you mean the Intake air temp sensor o-ring? 13621739510 . . . no part number for the DISA o-ring that I can find.
