What could cause a car to shake and shut off when stepping on the gas?

I'm not in expert, but it could be ( in winter time) that the car engine is still cold. But if its warm temperature outside, it could have something to do with the gas filter. Its probably blocking from the gas to get to where its supposed to go. It also could be your spark plugs, or wires from the spark plugs. You could check the spark plugs yourself. If the end of the spark plug is dark, like almost black, you need new spark plugs. If you look at the wire from the spark and its worn out, then replace them.

You will still have spark, car will try to start or backfire. If no spark at all the plugs see if you have GOOD spark from coil. If coil is working then you will find the problem in between the coil and the plugs, probably a distributor component issue. The ballast resister is a possible cause also.
