I have a 1997 Ford Taurus G (base model). It has new spark plugs and the plug wires are good, a new fuel filter, has had fuel injector cleaner and good 89 octane gas from a legit gas station run through it, has fresh oil, a recently flushed radiator, a new speed sensor, and a new idle air control valve. The car runs good once it's started. However, it idles a bit rough despite all of the above. Not high, but a bit rough. The problem is that sometimes it doesn't stay started when you start it and dies out after running like 10 or 15 seconds. This doesn't really happen that often. I haven't noticed a pattern, but the last time it occurred was on a semi-cold start in cold weather. I'm just wondering what this might be. If it's something cheap enough, I wouldn't mind getting it fixed. If it gets worse, I'd like to know what it is. I don't know what it could be. I doubt it's a compression issue because it runs so well once it's started and warmed up. I don't know much about this, but a coupe of possibilities that come to mind are the coil(s) (or whatever) and the fuel injection. What do you think?
