For the past two weeks my injectors have been acting up. I'm guessing its one, because I can still drive somewhat, but it cuts out every now and then. For a couple cycles or until I change throttle, it'll stay shut. The strange thing about it is that if I give some open throttle, or even 3/4 throttle, they all open up just fine, but when I return to regular cruise vaccum, it goes back to pissing me off. They're DSM 450's by the way.

I can only so far think of two reasons this is happening.
1. my wiring is crap. Maybe there was a slip between the resistors I wired in there, but that's unlikely. I went over it all again and it looks fine. Also my ecu (aem) isn't showing any faults, and is telling me everything is running as it should.

2. My injector(s) are clogged, and just need a cleaning. The thing with that is that I had them cleaned before I went turbo, just about two years ago.

anything else I'm missing? I'd love to hear from anyone who's got another opinion on what's going on. Are my 450's on their way to an early retirement?
