Hi, I'm from Antofagastas, I have a Hyundai Matrix 1.5 CRDI with 210000 km, I have changed spark plugs, injectors, valves, rings, fuel pressure censor. And the car is fine until one day it went out and I did not turn on anymore, it takes it to a mechanic managed to turn it on and it remains with pulls and emitting a lot of smoke, and the accelerator does not funeate, someone knows some data of the problem,
