Try this.... My 2003 Lincoln Navigator was manufactured May 22, 2003 so it's the late model that came with the Intec 5.4 Liter DOHC V-8 (not the Triton engine). I replaced the two front ride height sensors (one for each air strut) and replaced the one rear ride height sensor (passenger side) that controls the ride height for BOTH rear air struts. That solved the problem for a few months during warm weather, until the weather started cooling off. Then back to the same issue. The front passenger air strut started releasing air from the solenoid (air block) making a "hissing sound." Replaced BOTH front air strut solenoids (connected at the top of each air strut). That also resolved the problem for a few days. After going all around the world, I discovered it's the Air Ride Control Module (ASM) that was the problem all along. This is most likely the culprit for your air ride suspension problem.

Some starter motors can be a tight fit in the mounting hole. Using a WOODEN block or the HANDLE end of a hammer Tap the motor firmly, NOT hard, to the left, right, up and down. This should loosen the motor enough to slide it out.

Go to an Autozone, Advance auto, or Oreilys for a free Code scan. This will tell you some or all of the problems. Usually this symptom is a result of a bad O2 sensor changing the fuel mix (floating)from lean to rich or the temperature sensor messing with the "cold start sequence".
