Check engine light
What is your question?
My check engine light has been on for a while. Just last week I replaced the 3 coils, sparplugs and wires and also the air filter. I plugged in the code reader and it did not have any codes, but when I tried to remove the check engine light the code reader said it "failed." Any help will be greatly appreciated

Your "code reader" can not communicate with all of the onboard modules .. Recommend professional 'scan test' to determine what the fault is.

Do you mean a diagnostic machine test that a automotive shop would do?
Yes, 'most' up to date repair shops have the scanner that's needed... These scanners are pretty expensive but a necessary tool for diagnosing, testing and repairing computerized vehicles... The proper scan tool - in the right hands - can work wonders when it comes to fixing problems we have with vehicles nowadays!
