Shaking when on a dead stop, @ 500 rpm

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??

SOURCE: 2002 lincoln ls idling shaking when put in drive.

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.

SOURCE: 98 lincoln navigator loud noise, shaking, high rpm at idle, drive

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.

SOURCE: 2001 LINCOLN LS V6 - ROUGH IDLE / SOMETIMES STALLING.

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.

SOURCE: Why would a Lincoln Town Car 1994 start shaking as

hi,

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.

Idle is high at start - 1800 rpm. Seems like excessive white smoke from exhaust. Put into reverse and back out of driveway it has a regular shudder (bump bump bump) but not hard metal grinding sound.....


white smoke out of the exhaust would be a sign that it is burning coolant... if it goes away after it warms up, it could just be condensation inside the exhaust pipe. 1800 rpm is a very high idle, maybe have your IAC motor on the throttle body checked... check engine light? if so have the code read at your local auto zone.

After the engine start running for sometime it starts shaking.


hi this could be a few things, i would check your idle as a very low idle will cause engine shaking when the engine is near stalling, idle should be around 700rpm approx when warm. If that checks out all good check the leads and that one is not getting worn and causing a misfire or a vaccum hose is not off, both will cause similar problem. The last thing i can think of is a broken engine mount causing problem as when motor idles or runs at a certain rpm it will shake harder and may be the cause aswell

Try cleaning the throttle body plates with throttle body cleaner.Also check for vacuum leaks around the intake gaskets.You can also check for codes.Sometimes you can have codes and not get a check engine light.Hope this helps.Good luck.

Engine idling varies depending on light or aircon is on/off


dude its normal for first start or cold start that the idle is ok but it must high than normal... its normal because the engine is warming up it self... when it gets warm, the idle speed will return normal idle... your engine is 1200cc, it has not much HP for a great load... and i know its a carburatored engine and its an old engine, your head lyt and a/c fan and aux fan and all the electrical system on your car, uses the HP of you engine and its a lot of load to the alternator driven by the engine to generate an electricity they need and thats why the engine rpm speed lowering down to dead and its shake. thats why when you use your lyts or all electrical, you engine is weakening... the best remede is adjusting you idle speed... its located behind the carburator.. its a small black knob.. just make a twist each eighter way and you'll find out if your idle rpm speed ts incresing or decresing.. just increase it and try opening your lyts and other electrical, if its still shaking then adjust it a little more
