- Hey Scotty, I just cleaned my throttle bodies on my 2007 g35 sedan. Now it idles very high, I’ve tried the ECU reset procedure but it didn’t work. Was wondering if you had any other idea what to do? Maybe I have to get the ECU reset?

Have you checked your hoses and connections to see if there are any leaks?
