I have disconnected my temperature sensor and install an aftermarket gauge. I read that the sensor sends informaion to the CPU during start up. Does anyone know if this is true. I have new plugs, wires, ect. It is very hard to start, dies after a few seconds and is sluggish when it will idle. Once the engine has a small amount of heat it runs like a champ. Any help?
Thanks
