My injectors are about to go out, at least one of them, it's an ON and OFF thing, kind of hard to diagnose. I measured #4 and it shows 19 ohms. I'm planning to replace all 4 at the same time. I can get "new" injectors but they're from a 1.6L 98 Nissan Sentra. Are they similar to 1.6L 94 Nissan Sentra ? Same part number ? Will they fit my original fuel rail ? Thanks in advance.
