2004 Mazda MPV Question: No check engine light? but the engine is jerking

No check engine light? but the engine is jerking If the light's on, the light indicates that the computer has detected a malfunction in the engine/transmission control system and has no diagnostic codes and data stored which would be essential in diagnosing the problem. A technician with a scanner can access the diagnostic codes and data and then be able to give you a diagnosis. If no light, check out the ignition system. I think that misfire under load is usually poor ignition. If you want to find a Mazda specialist, here's our directory link for you: -
