Hey guys
I have a 2004 4Runner with 226,000 miles. About 800 miles ago my engine started misfiring and I got the engine code PO351. So I changed out the ignition coil and went on my way. About 200 miles later it came back up so I changed it again and also changed the spark plug. This was great for about 50 miles and then the misfire became a lot worse. I checked the codes and last week I had all 6 ignition coils go bad. (PO351 PO352 PO353 PO354 P0355 PO356) and also had the cyclinder 1 misfire code. (PO301) that code went away this week and now I'm getting error code P2241 and P2238. O2 positive current control circuit low bank 1 sensor 1. And also 02 positive current control circuit low bank 2 sensor 1. The engine is still missifiring. What in the world is going on with my car? Thank you for any help. I just don't think all of my ignition coils could have gone bad at once. Especially when one was replaced a few weeks ago
