Hello all,
I have a 2010 Toyota Prius II with 242,916 miles on it. At about 240,244 miles, I had a check engine light from cylinder 2 with accompanying codes from cylinder 1 and 4. I cleared the codes and changed the spark plugs and changed the engine air filter. A code came up for cylinder 1. I cleaned the mass air flow sensor. I waited to gather more information on how the car was behaving before doing more work. It stopped raining for several days and the misfires disappeared after a few days. Then it rained and the problems came back. Frustrated, I changed all the ignition coils even for the perfect cylinder 3 and blew out the spark plug wells for good measure. It rained again and I received more misfires. Now I’m putting the old ignition coils back in because I don’t want to damage the new ones. Plus, rust accumulates on the ignition coils. I’ve removed the boots from the old ignition coils and cleaned them with dish soap to remove any residue. I’ve also cleaned the edges of the valve cover holes hoping that creates a better seal.
I’m getting frustrated because I’m worried about my catalytic converters. Hundreds of misfires have occurred while I go through this process. Does anyone have any advice for me? Much appreciated.
