Seeing the check engine light's on, sent the car a toyota dealer, which changed the ignition coil of cylinder#2. A day after, the light's on again, the dealer changed the spark plug. Then the light's blinking in a few hours. The mechanic of the dealer did the compression test and saw #2 has 155 PSI and each of the rest cylinders has 188 PSI. I was told I need replace the engine since the #2 cyclinder's wall was worn.
What can I do? Thanks!
