``` Okay, I have a 1991 Chevy Lumina and I believe this wire is the root of my problems. I ``` wasn’t the one who unplugged it but it seems it was unplugged as an easy way to get around a problem. When unplugged the car runs but the performance is off, It doesn’t feel like it has the same power as it does when it’s plugged in and it also sounds different when in idle. When the wire is plugged in the car stalls while driving at random intervals between 1 and 10 minutes and needs to be jumped to start it back up. I will attach pictures of the wire and it’s location within the surrounding area. ---

That’s a fuel injector that’s unplugged. The car will not run well with it unplugged. It will only run on 5 cylinders. If the car stalls out with the injector plugged in chances are it is shorted out and will need to be replaced. All of them, actually. These Multec injectors were known for electrical failures. What happens is that since the car fires three injectors at one time, the short causes excessive current through the engine computer and that extra load finally shuts it down. There is no way this would cause a car to need to be jump started.
