Possible coolant temp sensor. Help!!

[ssigma6]

This week I removed my clutch fan and replaced it with 2 12in electric fans and replaced my thermostat that has been bad forever. I have a ka24de obdII in my car. I turn it on and it ran fine until it heated up. I have no way of scanning the car, long story. As soon as it heated up it starts to run super rich. At idle I read 12.4-14.3 at temp. Once I give it throttle it will dump below 10 and either bog out and almost stall and then sometimes go, but remain below 10 on my air to fuel. I'm thinking it is my coolant temp sensor that finally kicked it when the coolant finally heated up. This had happened in the past a few times prior to the repairs, but only for a brief moment each time. Any thoughts?

Thanks in advanced guys! I really need to get my car back out it's my daily.

Why dont you trying changing it and see? If it runs normal when cold but starts bogging hard when warm, then I'd start with that.
