My 2009 Toyota Corolla S is having a misfire on cylinder #3.

Question

The car is really shakey when it is in park. My 2009 Toyota Corolla S is having a misfire on cylinder #3. I've replaced the spark plug, replaced the fuel injector, and checked the coil. What else could be causing this problem and how can it be fixed?

Answer 1

How did you check the ignition coil? The most common cause for a misfire is the ignition coil. If the coil is OK, then you have to perform a compression test to check for blown head gasket.
