My 2003 lincoln navigator is going more than 40 mph. it almost feels like it isnt getting enough gas. friend of mind mentioned a censor, but i have no idea. when it takes off it goes slow but eventually gets up to 40 mph. when i try and go faster than that, my rpms drop and the truck slows. someone out there that has or have one and had this problem, please give me the game on this piece of trash thats breaking monthly like eggs.

Condenser? What type of condenser? The AC condenser is in front of the radiator. Condensers don't have fuses, they are like a radiator for AC refrigerant gas to cool it, before going to the compressor.

Your description sounds more like a torque converter clutch problem. It would explain the poor mileage, having to floor it to go. I suggest having the transmission scanned, looking at the slip speed of the torque converter clutch.

Replace the two upstream oxygen sensors
Replace all spark plugs
Replace all the cop ignition coils
Clean the MAF sensor
Check fuel pressure

pop the trunk n grab the ring that it latches into n i bet u can move it.... the bolts that hold latch vibrate loose

replace the throttle positioning sensor

Hi,


The check engine light comes on mostly when you have bad gas tank cup,or you don't tight enough the gasoline.Go to any auto-zone and request the obd scanner,at no charge just leave your driver license or credit card,connect the scanner follow the instructions.They will check up and the check engine light will come off in the next 3 to 5 days.


Thank you !!

check fuel rail pressure

your ECU is faulty.
New ECU and voila problem fixed

ohh ECU= engine control unit

secondhand with do just fine.

get it fitted by professional

check ur sway bar. the bolt probably came out, look at the front wheels behind the brake disk, you'll see the sway bar

The thing that most people don't know about air suspension is that the airbags are not meant to be in temperatures below 40 degrees and about 90 degrees. This affects Navigators more than I would like to mention. You will start having problems only when you are in those temperatures but then it will cause permanent damage. I would recommend going to strutmasters.com and checking out the conversion kits. They are powder coated American made steel coil springs. They are guaranteed to last the life of your car and can withstand any weather. I posted the link below so you can take a look. http://www.strutmasters.com/lincoln-suspension-parts-s/1.htm Hopefully this will help you Brent
