Pontiac Grand Prix Fuel Injector
Hello,
I am having an issue with a fuel injector making a really high pitched whirling noise. So, what I have done is so far is: first I replaced the o'rings. That seemed to help for a short period of time, like a day or so. So then I replaced the fuel injector. That seemed to help for a couple of days then it started to make the noise again. If spray starting fluid on it, it stops for like a couple of hours then starts to make the noise again. I am not a mechanic and am not sure what else I can do with this fuel injector to get this to stop.
