A little history: the car had a head and ring job a few years ago, and the throttle body was replaced six months ago with a TB from an automatic due to idle and stalling problems.
Not sure if the original TPS was kept or not. Previous owner claims he drove every day with no problems since then, but the first day I had it I noticed it idling around 2k after the engine warmed up and revving caused black smoke out the tail pipe.
Getting about 10 mpg. After finding a repair manual online I think that that thing in the picture is the Water Thermosensor. I'm wondering if this is the source of all my problems? Maybe the guy who did the work for the previous owner changed the throttle, saw it didn't solve the problem and then just disconnected the water thermosensor to get it working? This absolutely could be the issue. Without the computer knowing the temperature of the engine, it has to run in a "limp-home" or "open loop" mode depending on how the vehicle manufacturer does things.
This mode is usually very rich. It does this so that the engine will not encounter a lean state which can cause damage much faster than a rich state. I would suggest that yours is shorted internally, thus the reason why the car is not starting when plugged in.
And like I said, it goes into a limp home state when unplugged. You can definitely try testing it, but I think you are on the right track. If it isn't the thing, it is definitely a thing which is wrong and needs to be addressed.
