Well as some of you know i had the Knock and o2 sensor lights on. For the past 3 gas-ups i used Lucas Fuel injector cleaner aka tune up in a bottle. Well Last night my SES lights cleared, I good friend of my Uncles is doing the tune up at his shop which cost me 210 for the parts alone no Labor. Can blocked injectors cause the codes to come on this thing is racking every part of my brain. I also purchased some thing to clean my injectors.

I guess the short answer to your question is - yes, blocked injectors can definitely cause codes to come on. The question is if that is actually what is causing them to come on.

I would see if you could take it to autozone and have them pull the trouble codes that are in the system. Once you get those, you can post back here and someone would be able to tell if you if this was definitely the issue. I know advance auto parts and autozone will do that for free.
