I have an Elantra 1995 and when pressing on the gas pedal and the motor rev. it brings out black smoke from the exhaust and I went to Hyundai for repairing they said the motor wasn't adjusted and they did adjust it and it's much better and moving faster now and everything is ok but still the black smoke comes out can anybody tell me what to do to stop that smoke p.s Hyundai said that the exhaust pipe has stored a lot of carbon and by going and coming for long distances it shall disappear but i still find the black smoke after nearly driving 3 months continuously what could it be

Spark plugs has been changed to the original one
Gasket changed
Pistons changed
fuel filter changed
fuel pump changed
air filter changed


i will be very thankful to get advices i really need it i love the car it has been a lot of memories with it and i don't want to sell it cause of that reason

 

I'm guessing it is petrol as you mentioned spark plugs.

Is the oil level okay? Could be burning oil but the garage should have seen this.

Is the smoke similar to the black fumes a diesel emits when revved hard?

 

Hi!

No sorry it is essence, but know it is ok no black smoke but smell oil?

Is it normal?
