Most likely a bad Thermostat or Water Pump. Replace the Thermostat, the cheapest part, and if it still overheats replace the water pump.

shake the car and listen for the oil sloshing around.

to check oil start vehicle in park and let idle, open large allen bolt [normally 17mm] on g/box sump, oil should spill from aperture. if not top up until it does. this must be done at a temperature of less than 30 degrees celsius as oil expands at higher temperatures.

Your sensor is going bad or you have to change your oil.

check the fuses

Hello.

I'm assuming you have an auto transmission, if you do, then if you are lucky changing your transmission oil might do the trick.

If you want to try this, then you simply need to change your transmission oil drive the car for a few hundred miles and change the oil again, this has in some cases solved the problem but its not guranteed.

Ok you will have to have it scanned. It probably has cylinder misfire codes and random cylnder misfires. You could need spark plugs and or coils. The scan will tell you exactly which cylinder is missing. That will cure your problem and remember to change your oil and filter right before you go in for the smog test. Also if the car hasn't been serviced in a while it would be a good idea to replace the air filter and fuel filter.

You have oil leaks getting on the exhaust system, they are getting into the car, have the car checked over to find source of leaks.
