I just changed the fuel inject on my Ford Taurus X. I got a cyclinder 6 misfire and after i replaced it the engine wont stay running after I turn it over. It wont idle either. When i give it gas the engine revs but when i release the pedal their is a high pitched whining in the engine and then it dies. Any ideas? ---

Maybe the o-ring for that injector slipped. Did all injectors on that bank have to come out? ---

Try spraying some starter fluid in the area where the injectors had to be removed. If that makes the engine run better, the injectors probably aren’t sealed properly, which creates a big vacuum leak, causing the engine to run lean and very poorly. That would most likely be caused by a faulty injector installation, forgetting to install a new o-ring seal, etc. Anytime an injector is removed, a new o-ring seal must be used when you re-install it. And the O-rings usually are supposed to be soaked in gasoline for a while before installing the injectors. I removed & installed injectors quite a few times on my old VW Rabbit, and I know from that experience it isn’t a simple process to get them installed correctly. Often the O-rings would distort in the process. Mechanics who have done this job a lot of times have tricks they’ve learned to make sure the injector and o-ring seat properly.
