I think you will find it is called 'Limp Mode'. It is the Engine Control Module finding a fault so serious that is might permanently damage the vehicle. You need to connect it to a Scan Tool and read the codes. The codes tell you the problem and the fix.
A scan tool allows for the OBD II (On Board Diagnostics) codes to be read from the engine computer in a car. These are common electronic diagnostics tools used by automotive technicians. They are usually used when a check engine light comes on to determine the error codes associated with the check engine light.
They almost always connect via a standard plug on the divers side under the dash.
Most automotive parts supplier will check a car with complementary service to determine the codes stored in a customers automobile.
OBD 11 scanner reads from 1996 to later models, your car is obd 1 and needs obd 1 scanner there is other way but for that you need the automobil manual repair.
I cannot answer question 1 for you for sure, but would probably be 2 one before and one after the catalytic converter. But 2 you may need to reset the light, which may be as simple as disconnecting the battery for a minute and the connecting it again, but may need to be done with a scan tool.
As for the smoke, blue smoke is usually and indication that oil is being burnt, white is usually steam (either water or coolant).
First off you need to have the problem fixed that caused the check engine light to come on in the first place. Otherwise it will just come back on. If you have repaired the problem then try disconnecting the negative battery post for 10 minutes. If that does not reset the light then you will need to have it reset with an OBD2 scan tool.
well I would take it to autozone or your local parts place for a free scan, yes they offer a free check engine light scan, they will give you a diagnostic trouble code and or a short description of what is wrong, do not goto dealer please , rip offs if you ask me, then once you get the codes, you can bring them back to me and we will look them up
Your vehicle’s computer system has self-testing capability. When the computer senses that there is a problem with one of the components or sensors it stores the correspondent trouble code(s) in its memory and lights up the "Check Engine" or "Service Engine Soon" light to tell you that there is a problem and you need to diagnosed and repaired it. The list of possible codes number in the hundreds. The code itself doesn't tell exactly what component is defective - it only indicates where to look, or what engine parameter is out of normal range. You or a technician will have to perform further testing to pinpoint cause and the proper repair. The light flashing when you are driving indicates a more serious problem that should be fix right away or more problems can occur.

The over heating could be the cause of the light coming on, further testing is required.
