Question about 2004 Lincoln Aviator
The suv is running great it's only when the motor is nice and warm and regular 500 rpm idle that it starts to shake. one mechanic said it was a natural shake, but i don't believe him because i also have a 98 f-150 with a way bigger engine and it does'nt shke at all. can u help??
Hey i just had this same sounding symptoms with my 2000 ls. It turns out that the ignition coils were failing (2,6,8). Just replace all of them. All of them i got on eBay for 150 bucks when the garage quoted me 1100 bucks. Good luck man.

I don't know how much oil you had to put in but it sounds like you have maybe more than opne issue and both sound major. One is engine reving and speed not picking up sounds like trans problem. Two the engine shaking and making noise and being run low on oil leans toward possible engine damage. If your mechanicly inclined check all fluids and when checking trans fluid smell it. If it smells burnt the trans has been damaged. Check oil pressure and make sure coolant is full.You may have to take it into the shop.

Very common problem is about a dime size hole wearing in the rubber elbow on the PCV valve located on the driver side rear of the intake manifold.

if its a 3.8 v6 then check the EGR valve. the egr valve will get a hole in it an cause a huge vacuumn leak, and cause that. untill you take it in you can plug the vacuumn hose that goes to the EGR valve on the intake manifold, fix it soon.
