Thanks Alex. Looking at at you diagram there is a purge valve I found similar diagram (minus a clearer hose detail) it was called intake manifold runner control valve I xalled mazda with the vin# and they called it runner valve as well for $160 so I called a few parts stores 1 or 2 had runner valve others did not autozone has it as part pv780 for runner valve (my diagram which I didnt print out) and pv769 for purge valve (your diagram) tge one on there now is the purge valve is NOT the orignal I changed it last year and it is chattering again. My question although I think they are both purge valves which one is the correct valve the runner or the purge as of now I have evap leak and a dead cylinder#2 im going to check the coil but could this faulty valve cause any of these issues thank you for help

Hello again,

No, a faulty EVAP purge valve will not cause a single cylinder to go dead. When the EVAP system purges it is introduced into all cylinders through the throttle body or intake manifold. I would do just what you are doing for a dead cylinder. Check the Coil On Plug(COP) and the two wires and the connector. You might want to check on EBAY or Amazon for your purge valve as well. A lot of times you can get Original Equipment Manufacturer(OEM) parts are equivalent for about 1/2 the cost of getting them at a parts house.

Thanks,
Alex
