Black Smoke is unburned fuel, try a tune up to start with and replace the air filter. If it does not stop then check the injectors to make sure that one or more are not stuck open. You also must have an exhaust leak in the engine bay.

That engine is getting too much fuel. Check the air filters and the oxygen sensors. IT could also be the injectors.

P2138 is the an issue with the throttle position sensor. Age can cause intermittent failures. Probably the simplest fix is replace the sensor.

im afraid you have a blown head gasket white smoke is cause by antifreeze burning in the cumbustion chamber causing white smoke

signs of a bad fuel pressure regulator-- the vehicle will run rough, the engine will not start ( usually in the mornings,) many times engine starts but stalls shortly after starting. a bad regulator can result in fouled plugs. replacement is only cure. 1- black soot on plugs-2-black smoke from tailpipe-3- running rough-4- stalling, good-day! repost if need be.

The three most common colors of smoke that can be emitted from the engine and billow from the tailpipe are as follows:
1. White
2.Black
3.Blue..

Each one has its own cause and its meaning .Kindly let us know what color smoke are you getting.

Smoke oil? For what your thinking that is oil? Smoke coming from the tailpipe is not good news, but does not necessarily mean the engine needs rebuilding. First, you need to determine what color of smoke is coming from the tailpipe
* White smoke is caused by water and or antifreeze entering the cylinder, and the engine trying to burn it with the fuel. The white smoke is steam. There are special gaskets (head gaskets are the primary gaskets) that keep the antifreeze from entering the cylinder area.
* Blue smoke is caused by engine oil entering the cylinder area and being burned along with the fuel air mixture. As with the white smoke, just a small drop of oil leaking into the cylinder can produce blue smoke out the tailpipe.
* Black smoke is caused by excess fuel that has entered the cylinder area and cannot be burned completely. Another term for excess fuel is "running rich." Poor fuel mileage is also a common complaint when black smoke comes out of the tailpipe. Black smoke out the tailpipe is the least cause for alarm.


If you confirm us that is oil smoke, check and keep in mind that the car has many seals, gaskets, and O-rings that are designed to keep the engine oil from entering the cylinder, and one of them has failed. If too much oil leaks into the cylinder and fouls the spark plug, it will cause a misfire (engine miss) in that cylinder, and the spark plug will have to be replaced or cleaned of the oil. Using thicker weight engine oil or an oil additive designed to reduce oil leaks might help reduce the amount of oil leaking into the cylinder.

Keep us updated.

If it is a petrol vehicle is your choke stuck on? If it is diesel it is over metering, either way you will use a lot of fuel.

1. If the smoke is black in colour, check the fuel pressure regulator and all the relays for injectiors and fuel pumps.
2. If the smoke is whitish in colour, then either the exhaust or cylinder head casket may bad.
