I have a 95 gst. It has just been rebuilt but all the sensors keep going out! I was wondering what a map sesnor does and also what would my car act like if it was bad? Also Can yall tell me which injector sensor goes on which injector starting from left to right( by color of the wires on the sensor) Also Can yall tell me the order the spakr wires should be or where they go( may have put them in wrong cylinders> Help!

The Map sensor in our 4g63s are mainly for emission things so I read. It makes sure the EGR valve is working. Mine is just hanging on the harness in the engine bay so I don't get a code for it. Which I still got an emissions code anyways but we don't have emissions testing here so I took it all off. The MAF sensor after the air filter is the one that tells the ECU how much air is in the system in which the ECU uses the 02 sensor as well to calculate the fuel needed. Do a search on the map sensor and you might learn more about it ### I sure did. Hope this helps.

ok how about the spark wiring and the injector wiring? ANyone? I always thought the map sensor did do fuel maps or at leasst control the injectors?
