Mi carro paso inspeccion hace 3 meses, tenia 3 codigosproblemas en la luz de services engine que tuve que reparar
1.- Oxygen sensor
2.-Misfire cylinder 2
3.- Misfire cylinder 4
Hize tune up completo se apago la luz de services engine pero ahora se prende cuando ando en la carretera a mas dde 50 millas por hora, y cuando entro a las calles lentas se apaga , a veces queda apagada por dias y prende de nuevo. Puse la computadora la lectura dice misfire cilindro 4. el auto anda normal con la luz encencida o cuando este apagada, gracias

Misfires can be caused by worn or fouled spark plugs, a weak spark (weak coil, bad spark plug wire), loss of compression, vacuum leaks, anything that causes an unusually lean fuel mixture (lean misfire), an EGR valve that is stuck open, dirty fuel injectors, low fuel pressure, or even bad fuel.
