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 ...
