check engine light keeps coming on, had code checked and it says cylinder #3 missfiring, i changed the plugs, and light came back on, changed electronic coils all 8 of them, and the light still comes on, takes about 8-10 seconds to start and i smell alot of raw fuel, and alot of fuel and blue smoke coming out of the tail pipe. burning alot of gas as i drive also. please help thanks.

 

Do it yourself. swap fuel injectors and see if miss changes cylinders look at the injector its possible it hung wide open.
