How to tell if a fuel injector is bad? 95, manual transmission, over 200k miles. At idle, the engine sounds rough. The idle speed stays pretty steady, but it's got an uneven, lopey sound to it, sort of like a misfire. Runs fine as soon as I give it a little gas. If it was misfiring due to a problem with the coil pack, then you'd expect it to misfire at higher revs, too (right?) - so now I'm thinking fuel injectors. First of all, does this sound like a plausible diagnosis? Second, is there any way to confirm it? If this was one $20 part, I'd just replace it and see what happens, but I'd like to be sure. |
