Have it scanned for codes. And check the fuel pressure.

The 95 will not be scanable it uses the early volvo diagnostic with pins, next to the front left strut, remove the cap labeled A and connect jumper to pin 2 turn the ignition on then press the button and count the flashes and give us those details it will flash codes in a 3 sequence 1-1-1=Ok everything leads to a code common one is 2-1-2 lamda ( o2 ) just make sure key is off when plugging and unplugging that jumper wire !
The other possibility is camshaft Position sensor or crank position sensor.
