Hey guys. Currently have a 4.2 FSI Q-7. I've been having a intermittent misfire on cylinder #5, I have replaced the coil and all the plugs. I ran two bottles of techron through it to see if the injector was clogged and the problem went away for a few months. I've tried some techron again with mixed results... Anything else I should check? It is almost boating season and I can't tow the boat with the misfire

Had similar issue 4 weeks ago, one injector had to be replaced and the other ones not in the best of shapes.

So I took it to my indy today... in less than 2 hours they had it fixed. The electrical connector going to the injector wasn't clipped into place and worked itself loose. Reconnected it and everything is running smooth!

I wish I had the same outcome, excellent fix .
