I just bought the car. There is a sensor in front by radiator, IF that sensor is connected, car starts easy but runs rough by hesitating when you step on the gas, or will not stay running and stalling out. IF you manage ir keep it running its stuttring and backfiring and the I believe cat. Gets red hot. IF you disconnect that sensor car is hard to start you have to crank it for 20 - 30 seconds but once it start, it will run you just cant push gas hard or it will hesitate if you go at a steady pace it will run ok.?
