    The preheater is the problem! And yes, the preheater can be changed.

Check out the preheater for the choke circuit. It closes the choke to give a rich mixture at cold start.

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.

Repair shop told me I needed a one new coil pack and new plugs. My 2005 Lincoln Navigator has 90,000 miles and has never had "any" engine work other than basics needed. Should all coil packs be changed...


Just change the bad coil. Each plug has its own and there is no difference when you replace a single coil or all. They could have ripped you off with all new coils, but did not.

Replacing all the plugs is a good idea for the mileage and the access. The same main parts have to be moved to get at one or 8.

AC unit is blowing both cold and warm mixing as if


Sounds to me like you've got a stuck door. One of the doors in the air ducts isn't closing/opening all the way. Possibly stuck or possibly a vacuum leak or disconnected/broken vacuum hose. Only way to know is to pull the dash apart. Sucks but gotta be done.

How do I replace a coil for 2005 lincoln ls


You have 8 coil pack's, to remove undo coil harness then remove small 8 mm bolt slide coil pack out and replace with new one, if replace all do same with all, you will have to work it around fuel rail, but I have never heard of all coil pack's going bad.

2000 LINCON ls spits,hesitate,go out of gear,stalls,check trans


A couple of things worth checking out:
  1. If it only hesitates and stalls when its cold and smooths out when its warm, I'd check the MAP sensor and TPS
  2. If it's sluggish all the time and stalling, it's very possibly the catalytic converter
Hope this helps diagnose your problem. Best of luck.
