hi i have a 1994 protege and it's in my driveway for 3 weeks now. At first it stop on red light so i have to keep the gaz on always. I changed the gaz pump and work better. And after 2 days the same problem start over again. My mecanic changed the entire distributor, cable, plugs, heat sensor and did something on the injection. By the way there was no code on the CPU. When i started it alot of white smoke came out and after it rolle like new. The second time i tried to start at home just the starter is making noise and nothing else. I am sick of all this i think about put my car in junk now cuz all the mecanic a saw seams confused about this problem even the mazda dealer. but it is only 205000. Someone told me to change the o2 sensor or the computer. It is a good idea ? Thank for your help.
