car over heat temp on traffic
when on traffic my car temp go up and when apply the gas it go down to normal temp
I love my Mazda's.
Also check that the radiator fan is running. I had an old 323 once that about every year the fan would stop running, less a few taps with a hammer, and had to replace it. Same issue, heated up during a stop, and cooled down while driving simply because while moving air is flowing through the radiator to cool it.
If you can't find the issue, I wouldn't hesitate to take it to get it checked. The last thing you need is to get caught in a road jam and blow the head gasket.
