I have a 1998 Contour SE with 76k miles. About 5 times in the past year, with the 2 most recent being the past month, the car would turn over and shake violently for maybe 5 seconds at most then stop. I will replace the fuel filter tomorrow, but am still wondering if the fuel pump and/or MAF are bad. I was not able to listen to the fuel pump these times to see if it was working. I started the engine, then unplugged the MAF and the engine still ran, but a little more rough. Any suggestions? Thanks.
