On a recent cold morning, the car started just fine, but there was an obvious roughness to the idle. I let the car run and when I drove off - about 10 minutes later - the rough idle was gone. Didn't think much of it.

Two days ago after another very cold night, the rough idle was back. Drove around the block a few times and the rough idle eventually went away, but not before logging a few error codes.

I got a 4-5-3, 5-4-3, 5-5-3. All of these codes have a "misfire" issue and two of them are specific to cylinder #3.

I've never had to replace a fuel injector in any Volvo that I've owned and was wondering if this is a clear sign of an injector that is starting to fail. Could it just be clogged? My '95 850 just turned 132,000 miles and it still runs better than most new cars.

Have any other brickers out there had this kind of injector issues after surpassing 100,000 miles?

Thanks for any input.
