hesitation at startup, roads and on inclines
I just replaced my transmission. However my car is throwing a code 21 Main 02s and heater signal. I ordered the upstream sensors from advance auto and they should be in tomorrow morning. Do I cleaning connectors and do I clean the slot where the sensor came from prior to installing. Also what does heater signal mean? Also my car is not throwing out good heat. It does get cold in Georgia. My car stalls at starts and at interstate highway speeds. Help

When you say not throwing warm air, does the operating temp run normal? Prolly a stuck thermostat, or the heater control valve has took a dump. When the car stalls does it do it any speeds, or more than normal at other speeds, be more precise please. Will try to tell you the code tomorrow. I dont have the access to them now. I wouldnt think you have to clean the insert holes before installation. As long as the threads are clean, you should be good.
