Hi,

I have a question about my 99 S70. When I go on vacation for more than four or five days and let the car sit at home, during winter, and I come back and try to start it the engine sounds like it's going to blow up. It chugs and struggles and the engine light comes on momentarily then goes out. The engine quiets down to a rough idle. My car has 83,000 miles on it and I have faithfully serviced it at all intervals. I also change the oil every 3500 miles so it is a well maintained car. I must admit that I have never had one expensive repair issue with this car either. It's been wonderful. I guess my question is does anyone else have similar issues with their car ? Is the problem the winter additive that goes in gas in some states? I live in Va.
Also, shoud I just buy a gas additive to clean the injectors?

Thanks in advance for any responses

I have a S70 GLT 1999. I get the same problem you do. I learned to drive the car before i go on vacation. Let it sit until the engine is about 98.6 or body temp. than start the car for about 10 seconds and shut it off.

When i get back after 4-5 days it is a bit rough but not too rough. If i dont i get the same problem you do. Also i found some small bits of metal in the engine oil when i change it. As long as i do this procedure i dont get metal shavings in the engine oil. Also i use Mobil 1 5w-30 synthetic.
