About two weeks ago I did a tune up on my volvo and I changed wires, spark plugs, rotor and distributor and they were volvo original parts. After I did that the engine was like it never it was it was working very well. and and the problem started by me driving like at 50 mph then I push the brake and I accelerated strong and the engine was shaking but I was close to my home so I quickly went home the codes I got are p1310-p0304 please help me

There are no codes like that

I believe the OP must have meant P1310 and P0304. Those would indicate a misfire in #4 (P0304) and the P1310 can be either random misfire or a #5 misfire.

I would re-check your work. Make sure the plug wires are not pinched and are secure in the dist.cap. You may also want to make sure that the rotor is secure as well as the spark shield is seated correctly.

Good Luck.

Are you sure the plug wires are attached to the proper locations on the cap? The Haynes manual is wrong about the order of the wires, if you followed that it would be incorrect.

is your car a turbo or non-turbo?

is turbo

Since the OEM turbo plugs are single prong, I would check the gap. Sorry if you already did that, just trying to think of things ...

If the plug wires are in the right place, and the plug are gapped to spec, then I might even try swapping plugs to see if the misfire stays in #4 or moves with that spark plug.
