Due to a problem with my car engine, the car would not accelerate and would move slowly despite pressing on the pedal. The car screen indicated that it was PCM problem (the gas would not come up) and it was a reduced engine problem. The car not accelerating despite pressing the pedal can pose serious safety problems. I have not taken the car to a dealer to repair yet.

Every time I drive the vehicle for any distance or speed when I park I can smell fuel. The odor is very strong when I park in the garage. The Odor will last a few hours then go away. But if I have not drove the vehicle that day no odor will be present. It Is smelled back by the gas cap leading me to believe it’s ether the fuel hose receiver or the fuel pump that after investigation have found out the fuel pump is under the back seat on the passenger side. But it is important to note there is never a fuel smell inside the vehicle.
