well im getting a code 22 which is the coolant temp sensor,but i was still getting a good reading on the temp gauge then all the sudden the gauge went cold.so i bought the sensor but i looked one of the connectors came off so i plugged it back in and the gauge started reading again.i still replaced the sensor but the code is still there.now the car is hard to start when cold,and does anyone have the part number for that cold start injector sensor thats on top of the water outlet housing
