Q: Car running and idling rough

The car is giving me a code P1569, the engine is idling roughly, and the transition to over 3,000 RPMs is not smooth.

This is a common problem on this engine. When you get symptoms such as this with this code it is caused by an issue with the variable valve timing. Most of the time it is because the timing actuator has failed. In some rare cases it can be caused by the timing chain being worn out. A mechanic would pull the valve cover to inspect the chain and the actuator to see if they have failed and then replace what is needed. If this is something that you are planning on having done, consider YourMechanic, as a certified mechanic can come to your location and diagnose your rough idling issue.

Yes this is correct. The timing belt needs to come off to replace the water pump to prevent coolant from leaking into the timing belt rubber which will cause it to fail. If you would like more information on timing...

Hello. The Mazda parts catalog transaxle part numbers for the two years you cite are different. Therefore, these two transmissions are NOT interchangeable "out of the box." Sometimes the differences from year-to-year relate to electronics or controls which you "might"...
