HelloCustomer It is possible that an injector got clogged if the treatment loosened up some debris in the lines that then flowed into one of them .Here ishow to check this problem. With the engine running,disconnect the electrical connecter on the IAC, you can then pull a connector off the injectors one at a time with the engine running to do a blance test. If one has no or little change,the injector may be you probem. Swap it to another cylinder and if the miss follows the injector, replace it.
