I have a 2001 Mazda 626, and for about a month now I have had problems with it jerking/shaking. It started off only jerking when i was stopped at a red light or backing up, but recently it has also started jerking when i am driving normally as well. It seems to be worse when the AC is on, the car starts fine, but a few times it has squealed for a few seconds after i start it up, and then as i back out of my parking space it jerks.also sometimes when i'm idling it acts as if it's going to shut off for a minute but doesn't, then goes back to normal. i took it to auto zone to have them scan it and no codes came up. i have been told by a couple of people it could be my fuel filter or my spark plugs, does this sound correct? or do you have any ideas what it could be?
