98' XC70 Dies when you put it into gear.

[1998XC70-AWD]

Hello,

I just wanted to say that I am new to the world of Volvos and thought that I would give this forum a try. I had went to start my car last week and it was turning over but wouldn't start. Waited 15 minutes, and got the car started and backed up the car, but when I went to shift it into drive the car died.

After it died, I tried to start it it took four or five times and I was able to pull forward without it dying.

I have replaced the fuel pump relay, the fuel pump has great pressure and I have no idea where to start. The car is very random and will work perfectly fine half the time.

Throwing codes: P0410, P0305, P0300, and P0422

Any ideas?

Thanks!
