I was driving my 2008 ford edge and hear a metal sound like if it was scratching the floor.I saw under the car and it look like it was the drive shaft shaking in the front part that was making the noise,now i want to know can i just remove the drive shaft and make it fwd temporary so i can get the money to change the drive shaft(if it is the driveshaft) or anyone had the same problem or any idea what can it be and if it is can it be something less expensive to fix ?
My car key fell off and broke, I removed the circuit inside the key case to be soldered. Then I tried to start my car with just the key without the circuit situated inside the key case. The car started successfully, but dropped. Even if I throttle it, it won't raise. I started it again, it started, but dropped off again. The third time, no revolving again occurred. I called a mechanic who tried to hard_start the car. It didn't work that way. I tried to fix back the circuit in the key case, the mechanic put some fuse, so now the car starts well, steams, throttles fine but it's misfiring. The engine is vibrating. I tried to check the coils (plugs). When I checked them, one of the coils is not firing. No spark in the wire connected to the plug. There's no current coming to the coil. And the check engine light is On. Other coils are sparking, but one is not sparking. The sound of the engine is not stable again, reluctance in movement and the security alarm is off
