Hi guys
This is a first for me .Hope someone can help.
2007 f150 5.4 liter noisy when cold.the colder it is (say -25 deg c) the noiser it is.
When I start it and put it in gear the rpms drop to 8 or 900 and the engine
vibrates and sounds sort of like a diesel.If I increase the rpm it quiets down a bit.It seems the worst at 900 rpm.The whole truck resonates ,it's pretty scary.
When it warms up it"s a lot quieter,sort of a low pitch hum at idle speed.
My dealer has looked at it a few times but can't seem to find the problem.
No code shows up .They contacted Ford and were told to check oil pressure
when cold.
The problem started last fall and the colder it got , the noisier it got.
If anyone has come across this one ,please let me know !!!
Thanks
