my 95 mondeo is smoking and black soot is coming out the exhaust?

Question

when i press the accelerator its almost as if there is no power and i can hear a deep gush of what i think is air, also it has started smoking from the exhaust and leaving a black soot like deposit on the ground, drove it today and it seems to have lost a lot of its power, its a 1.6 petrol zetec engine, can anybody please offer some advice, many thanks in advance.

Answer 1

the o2 sensor may be bad. It sounds like its burning to much fuel.

Answer 2

I concurr with scottaich (thumbs up)
Black soot and loss of power suggests that your piston rings are worn or leaking badly. Take it to a garage that offers a tune up or 'krypton tuning' service.
If it's bad i'm afraid this won't fix it but it will give you a diagnosis of what's gone wrong.
From there you can decide how best to tackle the problem.

Answer 3

Sounds like you might need a rebuild on the motor, blue/black smoke usually means oil is being burned with the gasoline in your motor, the sooty stuff backs this up=burnt oil, probably bad piston rings/cylinder bore, that would account for the loss in power too, how many miles does it have on it?

Answer 4

One of your cylinders is choked with carbon.It is a common problem with the Zetec engine.I assume you a British,if you are it is quite an easy job for a garage and should cost less than 100 quid to rectify.

Answer 5

Well black smoke tells me it's fuel, and not engine oil which is blue, but without looking it's a job to tell ,Sorry

Answer 6

You could be burning oil.Have that checked first b4 spending money on anything else.My first car did the same thing and thats all it was.
Good luck!

Answer 7

It sounds like it's time to start reading the "Cars for Sale" adverts.

Answer 8

You need to get car anti smoking patches, your local mechanic or doctor may be able to help you.

Answer 9

It sounds as if your catalytic converter has had it
