I own a 2002 Mazda 626 and I love it. I bought it just about brand new - 1100 miles (it was a mazda employee's car) anyway. . . I am having a problem with it and I think it could potentially serious because the check engine lite was flashing. I'd be going at a normal speed (45-55mph) and it begins to buck and act like it's going to stall(but it doesn't). On my way home from work (I commute 30-35 each way to work) it began doing it real bad and that's when the check engine lite began to flash. I got it home and the dealership will be looking at it Monday. Now, I have kept up with the oil changes, the tire rotation and the inspection, but that's about it. What is going to happen to me if I didn't keep up with and don't have the receipts for the other scheduled maintenence that should have been done on my car - DOES THAT MEAN THAT THIS PROBLEM WON'T BE COVERED UNDER THE WARRANTY??? Any advice for me?? Thanks!!! (help)
