I have a 1999 v70 and my problem was rough idle. it went up and down while idling. I found that the butterfly in the intake throttle control was dirty and just needed to be cleaned. If you can take it off yourself and clean the carbon/dirt and oil and the butterfly you can save alot of money. you don't have to remove the intake as Volvo will tell you, all you need to do is be able to feel with your hands the bolts to be removed. and also the clamp that holds the intake tube. then just unplug the ETC and clean it up. DO NOT TRY TO REMOVE THE END CAPS OF THE ETC. there is nothing inside you can service and if you destroy it it will cost about $700 dollars to replace. good luck.

Why does your 97 Buick lesabre not start sometimes?
There are countless different causes of an engine not starting, but in general, if the engine is receiving fuel, has ignition and compression, it will start. Begin with the basics. Next time it won't start, try a little starting fluid. If the engine runs briefly with starting fluid, you have a fuel delivery problem. Then go on from there. The only way to find a problem like that is to break it down. Check your Cam Sensors sometime they have a loose connection, your engine has 2 sensors a primary and secondary if the primary is the problem your engine wont start if its the secondary i will start but will run rough
