Mazda 626 97 Acts like it's missing.
My 97 626 seems like it has a missfiring problem. But the plugs are
almost new. It used to be that it would shake a little at startup and go away in a few seconds. Lately I have been smelling coolant. Today I started it up and it did the old shaking thing but did not go away. Pulled all plugs, looked good and firing. Then noticed a crack on top of radiator hose. Question? Could this be the reason for the rough running? Lack of pressure build up in cooling system? Have not checked codes yet as I would have to buy a device. But want go the cheapest route in repairs first. David R. |

I diagnosised it to a bad sensor in the distributor. Forgot which one. They eventually took it to the dealer, and they found the same thing and fixed it. There was also an oil leak on the back bank that is covered by the intake. This flooded one of the spark plug holes. But that was only a contributing factor. |
