My 2000 lincoln Ls V6 started running rough when cold at idle but clears up when engine warms up. Any thoughts?

    Every motor I own runs rough when cold. May be the sensor. Sounds pretty simple. I'd change the oil and check the air filter.

Out of gap spark plugs and a dirty throttle body also plug wires or plug boots I don't have time to look up your car but this is most likely spark related if you have regular plug wires they are leaking through voltage and moisture under neath is causing them to misfire till the engine heat drys up the moisture then it runs like nothing ever happened this will always be overnight cold from dew getting into the engine compartment condensation from steam heat produced from late evening parking and early morning starting

That does not sound to bad may be tight motor (low miles) or broke down oil, (When was the last time you did an oil change w/ quality oil?) weak oil pump ( keep an eye and ear out for unusual engine sounds , immediately pull it over and try to get it towed to fix it..(AAA motor club?) either way if you listen to your engine you will figure out to crank it up and let it idle while you get ready to go (say 15 minutes prior to leaving home.) that way there is not significant wear on a cold start and go (like my woman) and like most people .Also when was the last time you did a tune-up?

Car runs great but on a cold start it has a rough idle like a bad plug or fuel filter replaced both after car is warn will start fine every time

has the engine coolant temperature sensor been checked to see that it has the correct ouput votage at the chart temps, if it is out of spec the engine can run lean and this would cause cold start issues, also what is the fuel pressure reading when key is shut off, does it drop rapidly? should never loose more than 5 PSI, if it does the fuel pump is defective, also a fuel filter will not cause hard start or rough idle, only overall loose of power, does it have that at anytime?

My 03 Lincoln LS started idling rough only in the mornings when first started. Rest of the day it starts and runs smooth.

Sounds like it might be leaking intake manifold gaskets. They leak when cold but as the engine warms up they swell and seal up. This is common with rubber intake manifold gaskets.

When I start-up the engine and put it in drive, I could feel the car raise up. what happened; it does not do it any more. Lincoln LS 2002 -V6

That feeling of raising up,only happens when your foot is on the brake and you pull up on the Electronic Parking Brake.

Also what you discribe,could be caused by starting the engine and immediately putting it in gear,before allowing the idle to come down.

I never start any vehicle and drive away. Even in warm weather I let the vehicle warm up about three minutes or more and drive slow for a couple of miles ,until it is in closed loop. That's when the O2 Sensor takes over and controls the fuel system. So forget about saving fuel by leaving on a cold engine. That is nonsense and not fact or theory based.

05 Lincoln LS 3.0 V6. Outside air temp 32F. Idle decay when cold

This sounds like you have a pcv hose that has become an open vacuum leak. It is located under the upper intake, or given the year your air filter box may not be correctly sealed and possibly have a mass air flow sensor concern. Any Check engine light or codes to work with ? I f you have further questions just leave a comment on my page,
