Hello All,
I have a 1999 Volvo S70 AWD Turbo that I just bought. The car has its check engine light on and is shooting out the following codes: P0036, P0135 (Bank 1, Sensor 2), P0014 Exaust Camshaft Position Timing. When the car idles it throughs out a lot of smoke of a whiteish color, it comes in big puffs everytime the car is stopped.


What could be the problem with this?

Thanks for your help, I did not show a dealer yet because I was scared that they would rack up a huge bill.

Thanks
