1990 Mercury Grand Marquis Problems

Wear on rear axle shafts may cause excessive play and gear oil leaks
Wear on the rear axle shafts near the bearings can create excessive play and lead to gear oil leaking past the seals. Gear oil will leak onto the brake backing plate, brakes, and wheels.
Engine Stalling and/or Hesitation on Acceleration due to Faulty Idle Air Bypass Valve

If you experience difficulty starting the engine when cold, stalling at idle, or hesitations during acceleration, it may be the idle air bypass valve. This valve helps the vehicle idle steady when the accelerator pedal is not pressed.

EVP Sensor Failure May Cause Drivability/Fuel Economy Issues

The EGR valve position (EVP) sensor can fail on this vehicle. The EVP sensor measures the EGR valve position and transmits the date to the engine control computer. If it fails, drivability and fuel economy can suffer, the Check Engine Light will commonly illuminate.

Hi i am 15 and this is my first car i paid $500.00 for it. it has a major gas and oil leak and had its tail pipe ripped off but, overall its a nice car. its got a 5.0 liter V8 in it. its extremly quiet for a V8 and with no tail pipe its still quiet. its also got ajustable air shocks. a mini air compresser kicks on when it runs. i think its for the shocks but it could also be for the vacume sys...
I REALLY DIDNT LIKE FORD OR MERCURY BUT THIS IS MY SECOND FORD PRODUCT AND IT RIDES SO SMOOTH IT LOOKS LIKE A LINCOLN RIDES LIKE A LINCOLN HAS ALL THE BELLS AND WHISLES.
