Question about 2004 Lincoln Aviator

3 Answers

I have a 2004 Lincoln avaitor and this week i noticed after sunday filling up with gas it started missing on my way to work monday am. when i got to about 40 to 60 mph the truck starts missing. It has 75k miles on it and i thought well maybe it needed a tune up. i got it out of the shop yesterday and it is still doing the same thin only now it has a rough idle and when I stop at a light it acts like it wnats to stale. I noticed too this am the emissions service light came on. Could this be bad gas, onset to transmissions problems etc.. your thoughts and suggestions would be helpful. I plan to take it to auto zone to have it read for codes.

Once scanned and the codes suggest missfiring, Check your ignition coils. There are one unit atop the each sparkplug, and it is recommended to replace all upon performing a tune-up (costly). Purchase them on ebay and save $$!!Ford/Lincoln/Murcury vehicles with DIS and COPs (coil over plugs) systems are known for these coils to fail around 70-100k miles, typical early symtoms are random sputtering/missfire around 40-60mph with foot slightly on accellerator. If this is the problem, it will progress to stalling, severe missfire, very poor MPGs, rough idle!!Hopefully this helps

One of the first things did was replace the plugs and coils for the misfires, correction some one else did the work. my new mechanic looked at both plugs and assures me that they are working properly. Are their any wires I should be looking at for stays, cracks that may create this problem.

Rough idle and engine light is on my 2003 aviator 4.6 engine

If there is an Auto Zone around your area, have the truck scanned for the DTC codes which is causing your idle problem. There are to many things that can cause your trucks idle to be rough. Once you have it scanned, we can address the issue and have your truck running 100% again. Auto Zone scan free of charge and can give you the step by step instructions to repairing and replacing the parts needed. Good luck and keep me posted, be glad to help.
