I suspect you mean EGR valve. Not sure what you're asking, but RockAuto carries parts for the EGR system on your car. See the link.

Probably the relay to make ur regulator come off and on to charge ur battery?

For a 1987 mazda i think there is only one o2 sensor thats located in the exhaust manifold if not follow the exhaust down and it will be in the exhaust pipe before the converter, heres a picture of it and this will help you find it.

heater core, heater pump, air buble, thermostat

hello, if you have a vacuum pull off choke, you can try replacing your thermal vacuum valve on the intake manifold, it fits with the slow rpm..s at cold start!! Good luck, cheap repair if it works for ya. marty
