This is a strange code that doesn't appear to have one definitive reason, it's a bit of "you have a bit of a problem, but we aren't sure". Just Answer dot com mechanic says it is the MAF Sensor.

AUTO REPAIR SHOPS CAN TEST FOR YOU

Rotors and Brakes yes, Timing belt No, the 99' has the Variable Speed Timing that changes the exhaust cam timing.

At the rear of the cylinder head on the exhaust side camshaft.

Most of the time this requires a replacement of the unit itself. This is a very common problem and can be confirmed by a diagnosis at the dealer. Installation of a new one requires a software download and must be done at a Volvo shop.

You need special tools to do this, you need a Cam Lock/Crank Lock set and a Pulley Block to hold the Variable Exhaust Cam Timing. Do not attempt to do this with out those tools. I have done it but it was 5 times the work and there is no guarantee of getting that Variable timing correct.

Sorry for the delay.

Try to check the battery and the alternator and the fuse make sure the battery connector is not loose.
