Smoke coming out exhaust

When I first start my car it runs perfect, after driving for a while it starts to heat up, and then it cuts off. When I go to start it back up it's struggle to stay started, black smoke comes out the exhaust, and when I go to hit the gas or switch gears it cuts off; can you please tell me what might be wrong with it?

Sounds like the catalytic converter is bad. You need to have codes checked. See if there was some reason that would cause a bad cat.

Testimonial: "Where can I go to have the codes checked? My car not overheating the termostat gauge doesn't go pass the middle point. Someone told me it can be my fuel filter becuase when I left up the hood I seen smoke and I smelt gas? What else do you think it can be besides the CAT."

SOURCE: won't start

Hey it sounds like either a battery needs to be replaced, also If the car has an alarm, does the alarm use a key-fob. If you have the key-fob be sure to deactivate the alarm before you start the car. If you don't have the fob than you need to do a couple things, first try and find a valet switch, it is either a button or switch on the drivers side up underneath the dashboard, this deactivates the alarm, than give it a try, if that does not work disconnect one of the terminals of the battery, than turn the key to the on position, reconnect the battery, than try to start the car. If this does not work look at getting the battery tested for CCA, to make sure it has the amps to start the car.

Hope that helps

SOURCE: The car had been running rough...bought spark

His is probably not want you want for and answer, but;
These are two of several signs of a blown head gasket; it runs rough because when the engine cools after running, it is sucking coolant in to the combustion chambers and wetting the plugs. Once started, the white fog is the heated coolant passing through the engine and out of the tailpipe.
Depending on how bad the failure is, you may also find oily stuff in your coolant overflow bottle and a creamy appearance on the oil dipstick. 
Sorry, this is not an easy fix; the head gasket needs replacing and the cylinder head and block should be checked for warpage before the engine is reassembled. When the gasket fails, the head will need resurfacing, the block may be still OK.

SOURCE: When first started black smoke

Black smoke is burning oil. Blue smoke is usually transmission fluid due to a leaking modulator valve in the older auto transmission. White smoke is due to water getting in to a cylinder from a bad gasket, cracked block or a cracked head. Black smoke from engines on starting and/or running tends to mean there is fuel leaking into the engine, or the fuel mix is incorrect and not atomised correctly. the main causes are normally a nakered air filter that isnt letting enough clean air into the engine to mix. a blocked fuel filter, which is either not letting enough fuel in, or in some cases, a faulty fuel filter which is letting too much fuel into the engine, and causing black smoke due to excess burning. Black smoke is a fuel/air mixture suggestion problems with injection or carbonation. Cause of black smoke is due to running rich in the fuel air mix. Check the oil,the oil leak,the air filter,the fuel pump and fuel filter to confirm the fault.

Will only stay running on revs over 2000rpm if I take foot of peddle it cuts out also white smoke from exhaust

What is year--make--model?
Are you losing coolant? The white smoke may be coolant in the combustion cylinder, possibly caused by a head gasket problem. If head gasket problem, fix that first.

With idle issues, clean/check anything that has to do with idle air system. Any applicable trouble codes?

White smoke on start up

white smoke is a sign of water in the exhaust , the question is how is it getting there , if only when initial start then goes off then it's only condensation in the exhaust system heating up and turning to steam , if it goes on when driving check coolant level and check engine oil for signs of coolant contamination

White smoke came from the exhaust pipe and the car killed in motion. I check all fluid levels were fine, once i started the care again and proceeded the accleration was a bit rough. After a few minute

white smoke mostly is caused by over fueling so what i suggest you do is first of all check if there is no leak on the injectors and if there is none which means your valve sterm seals are damaged.When the head gasket is blown out you may have problems like :-loosing power when driving,over heating,idling problems and oil mixing with water, its not your head gasket.

I have a 1993 ford probe gt.. its starting to smoke under the hood by the passenger window its a light smoke it has an oil leak too.When I turn on my vent the smoke comes out this only happens when car...

you have an oil leak and when you step on the gas pedal the preasure inside the engine makes the oil come out faster and when it hits any part of the exhaust it starts to smoke i would find the leak and replace the gasket

Volvo 850 smoke coming from exhaust manifold

Not to worry. Run the engine up to operating temp before jumping to conclusions and let the heat burn off any excess oil. A leaf will not do any damage.Do not let the engine overheat while idling and if the oil light comes on switch off immediately.
The smoke from the exhaust is oil deposited by oily assembly hands just burning off. It should dissipate after about 15 minutes at most.(or 5 miles' drive)

White smoke coming out of the exhaust when starting the engine?

Its the problem of oil.The oil is getting burned out. The vehicle is either burning oil or it is moisture in the gas chamber if you notice white smoke from the exhaust. This is a common possibility.but in some cases this white smoke is not due to oil burning.In that case   White smoke from the exhaust is a symptom of coolant entering the combustion chamber. Normally this is a sign of a blown head gasket or cracked head. And  this is not a common problem must be repaired immediately. You must STOP driving this vehicle or you will cause serious engine damage. you will have to get both this possibilities checked.

My navigator wont start. it turns but wont fire. it happens every few weeks, and then when it finally starts it has dark smoke come out of exhaust. when i drive over 65 it hesitates as well. no check...

Have you had them check the fuel injectors? Might need new plugs as well. The dark smoke it the casued by flooding it when youre trying to start it and it has to combust all that fuel. The fuel pump might be going bad as well. Have them done a fuel pressure test? I'd need more info on what has been done to narrow it down a little more.
