I *heard* that the mitsu fuel systems were finicky when it came to voltage. Now, even keeping it on jumper cables isn't enough. This is kind of far fetched, but I'm going to clean them myself once I have some damn time, blow out anything in the injector with spray cleaner/air compressor, and then clean them in techron injector cleaner. And my new clips are coming in too. I don't really understand why that would matter in the functionality of the injectors except for no power getting to them because they were loose. But we'll see. I need to get the RX-7 running properly before I do anything. Once I do the hackjob repair and cleaning, I'll let you know. thank you!!
