Question about 2004 Lincoln LS

2 Answers

I have a 2004 Lincoln LS 3.0 6 cylinder. My wrench light

I have a 2004 LS 3.0 6 cylinder. My wrench light goes on while driving and the car goes into safe mode, 5 mph. If I put the car in neutural and restart it is fine but the engine light is on. It runs fine but this happens at least once a day. I put a new master flow sensor and throttle position sensor on but has not resolved the problem. Any help or suggestions would be appreciated.

Misfire cylinder lincoln ls

Misfire is almost always bad spark plug and/or ignition coil. I wouldnt trust an OBDII scanner to correctly diagnose which cylinder is misfiring. Your best bet is to replace the coils in all 8 cylinders (or 6 if its a V6) since when one goes out it makes the others work harder, meaning that they arent far behind

When driving on the highway and car is kind of jerking like is does not want to go any faster!

Bad COP Ignition Coils (cylinder misfires) even if you have
no wrench on the dash (check light)

Check with scanner in MODE $06 on a road test
or use an oscilloscope on coils

Egr Valve -- not any good also ,if it has been there since 2004

My 2005 lincoln Ls check engine light and wrench light comes on. the first time - a ford tech. changed a spark plug& wire. the second time a different spark plug & wire. third time another spark...

I have the same problem. My Lincoln Ls wrench light comes on and it quits. All spark plugs, all coils and the throttle body has been replaced. I think the LS model is a lemon! Any information or suggestions will be appreciated.
Thanks, Betty

Check wrench light on lincoln ls 2004

The check engine light comes on to alert you that the computer has noted a fault in one of the car's systems. Take the car to an autoparts store and have them scan the computer for any codes it has stored. Most parts stores will do the scan for free. The codes will let you know what the computer has identified as a problem/potential problem. Hope this helped and best wishes.
