Hi guys!
So after 1 year of problem solving the my 06 tl is almost like new.

I've finally cleared that pesty Lean Bank 2 code. Turns out It needed a valve adjustment. But in the process of figuring that out I changed spark plugs (months before my lean bank problem was fixed) and o2 sensors as well as all engine mounts and upper tranny mount mount

The car vibration has gone down alot since last yr but at idle the steering still vibrates a bit and the engine feels like it's miss firing. It's driving me crazy.

When turning off the car it has a 'diesling' effect. (rumble, shakes, then stops)

I thought it was related to the lean bank but apparently not

What can it be! Bad Coil pack? Plugs bad already? There's no misfire light.

 

Check your motor and transmission mounts.

I stated the 3 Engine mounts and upper tranny mount are Brand New

 

Maybe a vacuum leak? Any of the intake hoses ripped or broken? Checked all of the coils to make sure they are sparking properly?
Fuel pressure ok?

 

Did you replace them with OEM mounts? Aftermarket mounts are typically not hydraulic and can cause vibrations.

 

I won't lie. The front tl mounts are oem. But the side mount is not oem but that one isn't a hydraulic mount anyway so I don't know it that's causing the vibration?

 

The side mount is hydraulic, it just doesn't have a vacuum line. They're filled with fluid.

 

No CEL, but did you check for any codes?

 

No codes in computer

 

Now this is good to know. The mount I got for the side has no fluid in it. Its just rubber.....
