2009 GL320 Bad Injector
Hello all,
I have a 2009 GL320 as well as a 2008 ML320 - Struggling a bit to narrow down an issue on the GL, but at this point I believe at least part of it to be an injector with an internal leak. I already replaced one injector that had completely failed and was causing a misfire.
Question - With the injector out of the car, when blowing compressed air into the return line on the injector, would air pass through the feed? I pulled injectors 1,2 and 3. On two of them, If I blow compressed air into the return, it blows out the feed with little restriction. On the third, if I blow air into the return, this doesn't happen. Or, is this normal for some reason?
Thank you!!!
