Hi guys and girls, I have studied tested and dreamed Mazda triBute egr running faults and testing.
I hope this saves you time and money as there are so many misleading posts and threads as our mazdas do not conform to usual methods.
Tribute 2002 with erratic idle, found leaks and changed the hoses, idles perfect now.
Common leaks include hoses and gaskets.
Now have stumbling and lack of power under acceleration.
Whated a vid saying a healthy egr will stuble idle if vacuume is applied to egr, mine ran smooth still?
Another vid told me to take out egr and clean it out, it was already clean?
I watched another and it suggested making another egr gasket without the hole. Cutting of the flow. If engine runs cool then your egr is stuffed. Test drove and the misfire kangerooing went but the engine seriously lacked power and felt totally off but smoother than before.
Next was to clean out carbon deposits from the intakes in the engine. When the ports clog the fault code says emissions and the system is imbalanced with ports clogged at different stages, if all ports are blocked then engine will run smooth but will fail emissions test.
All over the web people show the simple job of cleaning the ports on other cars but our Mazdas are nothing like other cars and the ports are not in the head or accessible at all.
Preforming the simple tests in this order will get your car diagnosed fixed or bring you here to clogged port hell.
This is where I am at, so advanced advisors help needed pls.
Other clues are, the suction in to the sensor right before the egr is way stronger then after the sensor.
Adding suction to the egr makes the engine totally cut out?
Blocking the egr with a whole less gasket in the egr make the running under powered but no jerking at acceleration.
