The engine control system "learns" and adapts to the engine. As the engine wears it may need more fuel to run properly. Since there are no longer any adjustment you can make the engine management system adapts to compensate and make it run properly. Replace the battery and/or have the charging system tested first. after that is sorted out drive the vehicle for 30-50 miles and it should start to run better. Also NEVER jump late model cars as the alternator will go to full output once the jumper is removed which can spike amps to 150-175 amps all at once which can cause damage.

May have done something to the electronic ignition system. You may have to go to a Volvo Dealer to reprogram. Try a new battery first. My Ford had a dodgy battery and run rough as. A new battery, and she ran perfect again.

SOURCE: My 2000 volvo S80 2.9 seem to go into a safe mode

your car is going in "limp" mode,
the computer is seeing a problem with a sensor on the transmission,so it won't up shift because it doesn't know how fast your going.
check the speed sensor,the input sensor,and the output sensor.one of these is not working correctly,
it will help when you have the car checked for codes,look for history codes section.
cycling the key resets the soft code but it will always return until repaired.

If you are talking about the thermo electric cooling fan, its operation is independent of the car's electical system. It is switched on and off by the engine temperature. When you park, the engine heat soaks upward to heat the thermostat turning the fan on. It will run until the engine cools down and the thermostat switches it off.

Check your fuel vapor recovery system, your van has unusual set up, and the effect is RAW fuel gets purged, rather than vapor.
The dead giveaway test is does the issue happen on light acceleration? Does it stop if you let off the throttle? Can you accelerate harder and "get past" the issue?

My 2002 volvo s80 has to be jumped started every time i turn off keeps running after jumped


Check charging voltage when running. It should be around 14 volts at the battery terminals. If not, even when revving, then change the alternator.

Then check the battery voltage at rest, a few hours after resting that is. The voltage shouldn't be lower than around 12.5.
You can double check battery condition by turning on the vehicle lights and cranking. If the lights dim significantly, then you have a dead battery and you will need to replace it.

Emergency fuel door release for 2000 Volvo S80


Copied from Volvo Forums


I had a similar problem w recently bought 2003 S80.Several points: 1) Access your locking selonoid through the trunk interior panel ... loosen a few hex bolts and slide out for maintenance; 2) I fixed my lock by simply using light teflon-based oil (like for bike chains). I exercised it a few times and it works beautifully; 3) Not sure on your model, but gas door on the '03 unlocks when you push the associated release button under the headlight control switch. It is not designed to unlock w the key (again, check owners manual for your year). Hope this helps. master_pre08-04-2007, 09:35 AMYeah, the fuel door on my 2000 S80 is connected with the door locks. In order for it to open you have to unlock all the doors to the car. Sssnake08-14-2007, 03:39 PM Thanks Guys,

I removed the locking mechanism and applied a little silicon graphite and now it works like a charm.

Why does my 2000 volvo s80 starts for 8 consecutive starts


My suggestion would be to first check the battery terminal ends out or better yet, replace them with new ones. Either way, after removing the terminals from the posts, get a piece of sandpaper and clean the posts until you have nice shinney battery posts. Then make sure the terminals if using the old ones, are the same. Nice and Shiney and then make sure that after you tighten them down, that you are unable to rotate the terminal ends from side to side. This is just a basic starting point, but it is a very important one. Good Luck.
