Car will start if you step on gas peddle pressing it to the floor. makes loud knocking noise and black smoke comes out exhaust engine light flashes for 7 to 8 times can't tell for sure how many exactly. can you give me any ideas?
Its sounds like toms right to me. you should get it checked for trouble codes and that would probly help figuring it out. if the engine is knocking though, the knock sensor will retard the timing. its possible to get knock if the timing or fuel is way off. or there are internal engine problems. dosnt mean the engine is shot
Black smoke is NOT from oil, either leaking past the rings or the valve stem seals. Such leaks cause a light gray/blue smoke. Black smoke is carbon and comes from unburned fuel, running far too rich or cylinders not firing and dumping the gas out the exhaust.
Your engine is toast. The black smoke indicates more than likely your valve seals are leaking oil into the combustion chamber or the piston rings are shot.

have you checked for any trouble codes, if not buy a OBD II code reader and get back to me with the codes. Thanks
my service engine light has been on and this morning on the way to school it felt as if the car was slipping or jerking every time i pushed the gas peddle and then the service engine light started flashing but when i pushed brake it would stop flashing, what does this mean?
CAR SOUNDS FINE WHEN NOT PRESSING ON THE GAS
it dosent do it when im not stepping on the gas and there is a little bit of a ticking noise also
