This is an engine that is running very rich. Check the throttle body and also the TPS. Check all the spark plugs.

Could be a bad catalytic converter, check under the car and see if they turn a hot red color.

Check fuel pressure regulator by removing the vacuum hose. If idle does not change or fuel comes out of regulator replace it. Otherwise check your injectors one at a time while car is running. If idle does not change replace it.

four cylinder?

It is not uncommon for these engines to start to "burn" oil. Check the oil level and confirm that it is low. If it is make sure to top it off and monitor the level.

Next time you change oil try using a oil designed for high mileage vehicles. We have been using Mobil High Mileage at the shop with pretty good results on higher mileage engines with oil consumption issues. We have have several of the same vehicles as your use the product and it has helped them as well. It can't hurt to give it a shot.

Where is the fuel regulator located? And how can I tell if it's bad

Some fuel regulators are located in the tank as part of the fuel pump assembly. If the fuel pressure regulator has gone bad, it can leak fuel in the engine, contaminating the engine oil.

Symptoms of a bad regulator is:
Poor gas mileage.
Smell of gas in the engine compartment.
Fuel is leaking.
Black smoke coming out of the exhaust (tail pipe).
Failed emissions test.
Check engine light is on.

I have a 2000 volvo S70 i smell fumes in side car when driving went to get exhaust checked no problem there what can the problem be?

What type of fumes are they exhaust or oil burning.
Exhaust ..Idle engine and put glove on hand put hand over the tail pipe and if engine stops in 20 seconds then the exhaust is good if it keeps running then its the exhaust is your problem..
2 if ex ok then its due to the breather pipe on the engine and it should go back into the inlet manifold to be reburnt but if its not fitted or rubber hose split or broken then thats what you can smell.
So check out under the bonnet and see if you can smell or see any smokey fumes or sucking noise.
Can you see smoke when you start engine.
Let me know ASAP Ron

1991 toyota supra blue smoke from tail pipe when get of the gas

The intake valve guide seals are worn and are letting oil slip by under high engine vacuum--as when you let up on the gas. The only fix is to take the cylinder head off and replace the valve guide seals. This problem is pretty normal for an older car with high mileage. It will probably run just fine. Just keep checking the oil level and keep it topped up.
