It could be a number of things but must be diagnosed via computer code check. If you are unable to do so yourself, find a reputable Volvo mechanic. It could be the air mass meter, a bad O2 sensor or something related. Mine turned out not to be the air meter but a bad ground wire going to it. Didn't find out until $400.00 later.

Truck starts but only chuggs and blows out black gas smoke as engine lite flashes no throttle response


black smoke is too much fuel
check for leaking injector and injector seals
check for excessive fuel pressure
run the fault codes as you will have some from the engine light on

1997 Buick, Gran Sport. Returning from a short trip I stopped to get gas the check engine light came on. I checked the gas cap but the light remained on for the rest of the trip. Any thoughts?


Could have been the gas cap. You'll need to get the engine computer scanned for trouble codes to find out. Once the problem is fixed, the codes must be erased to make the light go off.

How to stop black smoke coming out of the exhaust


Put 93 octane gas in it. If it's blowing black smoke then the valves are really dirty and the 93 octane will clean the intake and exhaust valves off. Make sure and run it almost out of gas so the old gas doesn't mix with the new.

I am experiencing problems with my BMW 320i - 2004 model. It does not start easily. When it starts, a blue fuel smoke comes from the exhaust. this causes the car also to be heavy on fuel consumptio


Blue smoke is caused by oil. Rich running causes black smoke and will set the check engine light. Rich running (black smoke) on startup could be caused by a leaking injector. The blue smoke puff at startup is likely valve stem seals leaking or a bad crank case vent malfunction and sucking oil into the manifold at high vacuum conditions.

Engine running rich


The only thing I could think of to make it run rich is if the pump is wrong for the car, or something happened to the return line to the tank. The pressure regulator should maintain pressure, and the injectors should be functioning as before you changed the pump.
Is the check engine light on, and is the fuel pressure normal ?

Have 82 ford truck f150 runs for abut 5-15 mins than dies getin gas chang full pups two times same thant runs and die


Hmmm...maybe piston ring failure, valve seal failure, rich air/fuel mixture or maybe a head gasket (however that is normally white smoke due to coolant burning instead of oil). If it's so dark that it's almost blue then I can tell you that somehow oil is getting into the cylinder and burning alongside the air and fuel. Your best case scenario is that the engine is running rich (Rich:Too much fuel, Lean:Too much air) and the smoke is a dark grey to black color. CAUSES OF SMOKE

Hi guys...my yaris is running rich, has poor gas mileage (360km on a full tank). and very slow and choppy idle (idles like a really old car) these are the things i have done so far : change air and fu


Do the following:
1. Clean the throttle body from inside.
2. Adjust the spark plugs gap to 1.00 mm.
3. Check fuel pump pressure. (44 Psi - 49 psi)
4. Remove the negative battery terminal for 5 minutes.
5. Connect the battery terminal.
6. Check the engine oil level and coolant level.
NOTE: Before starting the engine shut off all lights and loads for example room light, blower, radio, parking light etc.
7. Start the engine and hold the throttle at 3000 rpm till radiator fan comes on.
8. After the fan comes on release the throttle pedal and let it idle for 10 minutes.
