pulsar running rich..cold start issues!!!

So every time I start my car in the morning it idles a little rough and when I put my foot down it chokes and bogs down until it reaches a high RPM or warms up. I have a CA16DE 87 pulsar..I keep reading to replace the "water temp sensor" and "coolant sensor"..Are those two different names for the same thing? Because that's what my mechanic said..I bought a "water temp sensor" and my mechanic replaced it. It looked like the one he replaced was near the top left of the engine..

I also bought a "coolant sensor" and he said I didn't need it because he already replaced that with the other sensor. Where are the locations of these sensors? I want to make sure he replaced the right one because im still having issues. My car has also been running rich and blowing some black smoke. I replaced the 02 sensor and getting new spark plugs and thinking of running some fuel injector cleaner through the system.. Thanks for your tips and advice..

There should be only one related to the ECM, don't know much about this engine, but the E16 had it on the back of the intake. there are two other coolant related sensors, but one just works the fan and the other only works the gauge. If it's blowing black exhaust and you already did the oxygen sensor, I'd look into your fuel delivery, I'd think the regulator. The car can still run, just terribly.
