    P0304 and P0306 misfiring and compression on both cylinders is 0. Both lifters have broke and collapsed. It started with a noise, once checked by the mechanic, we were told the lifter was going bad, before we could get it repaired it completely broke and that is when the check engine light came on and went off repeated times. At this time it is pouring out black smoke when driving and must have a complete engine replacement. The replacement work has been quoted for $10479.57.
