OK so today I go out in the am to start the bronco at 55 degrees.
It always starts fast and does a little surging and then to fast idle. This time it ran rich ( black smoke ) and shaky the whole 15 minutes I ran it. Engine light eventually came on. I felt the radiator hose as it warmed up and I think the thermostat is working like it should, but I could feel some warmth in the hose about 2 or 3 minutes after I started it. ( I am getting an OE 195 soon, and it will be tested in hot water first ). I shut the bronco down and let it sit until late afternoon. I removed the original ACT sensor. It had a light black film on it so I carb sprayed it clean and put it back in. I started it up and it went to fast idle as usual but did not put out any black smoke at all for the 15 minutes I ran it. It idled down to 850 and was smooth. Is the car confused or just me !!
