Outside Temperature dropping and "D" vibration increasing could be clue....

[2001LC]

Outside Temperature dropping and "D" vibration increasing in frequency & intensity. ("D": vibration while idling in gear with brake on)

Some mud members which includes myself, have noticed vibration not present or lessened if driving hard (high rpm driving like when driving with OD OFF). It is certain driving hard increase operating temperature of engine and transmission.

1) What components, sensors, meters, relays etc... are affected by outside air temp & engine temp?

Have done all the usual; Checked engine mounts, 44K, Sea Foam, MAF spray cleaning, Throttle body throat cleaning, PCV service and oil & filters. With some improvement in reducing Vibration.

If you keep all this stuff in one thread it makes it a lot easier for people to see the history of your issue, what you've already tried, and to make recommendations. Also makes it great for the next person coming along to have all the info in one thread, not spread out into a dozen.

Ya I agree and I'll update the thread Vibration and shake at Idle with what we gather here on this more specific temperature question, if that's OK. Unfortunately no responses to my question on page 3 over there.

I'd really like your input Monkey.....

It's only been a day since you posted in that thread. Maybe give people some time to respond before starting another thread.

Ok, if you'd like to delete this thread go-ahead and will see, it's fine with me.
