What owners wrote
When the 1998 mercury mountaineer was running on hwy 121 south merging into hwy 114 west in grapevine, tx, the 1998 mercury suddenly became out of control at a speed less than speed limit. The car was being accelerated even if the accelerator pedal was off. The driver applied break to stop the car but the break did not work. Then the driver had to steer the car into the bush off road to avoid collision to other cars. The driver changed the at to p (parking) to stop the car.
One of the braided stainless steel fuel lines that attaches to the engines fuel rail developed a leak. I kept smelling a strong odor of gas, but I could not find out where it was coming from. After two weeks of smelling the gas, I took it to a garage and they showed me the gas squirting from the braided hose going to the engine. I took the vehicle to the ford dealer and showed them the leak. They took the vehicle in their shop and removed the fuel lines.
