The car will run fine, then engine will start to misfire. Then lose power (put the gas petal to the floor and car does not move and the engine does not rev up due to the increased gas flow. ) the engine will shutter and turn off. Le it sit for 5 to 10 minutes and the car will start. The car will drive for another 5-10 minutes and shut off and will not run for start for several minutes and will not drive beyond couple hundred feet.
