what is the common cause for random miss fire on a 2009 toyota rav 4 2.5 engine

Answer 1

HI there

The most common issue for this type of misfire is usually either a bad ignition coil or worn out spark plugs. The computer isn't able to determine which cylinders are misfiring. If you have codes that point to specific cylinders then you can focus on those. Sometimes a slipped timing belt can cause misfires as well.
