I have a 92 Subaru Legacy that runs very well in mild weather but has developed cold start problems during the last couple of years. Anything below 25 degrees Fahrenheit and the car will not start. It cranks fine. I've changed coolant sensors three times, plugs, wires twice, coil and just last week had the dealer install new fuel injectors. Nothing has fixed the problem.
In addition, after the new fuel injector installation, the car engine is periodically stopping while being driven. The car idles fine but while underway, the engine just stops for about 1/2 a second then resumes normal operation(enough for your head to bobble). No alarm lights come on when this happens. The only instrumentation signal is in the tach which shows rpms dropping about 600 before returning to the previous operating level. These events occur at various speeds, 25 mph or 60 mph, from a start or while underway at highway speeds.
I can live with the cold start but the period engine stops is dangerous. Last week I was pulling across a lane of incoming traffic when it hesitated.
The car has 168,000 miles and has been well maintained over the years.

The rpm's dropping below 600 then going back up is the key to the prob. I had a '98 Dodge grand caravan, & now have a '99 Jeep cherokee that both had the same issue. I can't for the life of me think of the phrase that describes this problem, but IT IS correctable. I'd talk to the manager of your Subaru service dept, he'll know what it is instantly. Let me think overnight & I'll probably come up with the specifics for you. What the hell was that problem called?...

My nearest Subaru dealer has the car. They've been stumped because the cold start and intermittent stop problem doesn't have any ECU codes to explain.
Hope to find more from them next week.

There is no one common problem for any one symptom across car lines when it comes to drivability. I have seen several cold no starts on subarus and they both turned out to be the fuel pump, but that just what I have seen
