Default 2000 volvo s80 with codes

I am sure this is probably in the wrong section but I need some help! I recently bought a 2000 S80 (non turbo) with 120,000 miles on it. It sat for 2 years without running. It barely had gas in it so I put 10 gallons of gas in it and it fired right up. The ABS module was bad and I had it repaired...that problem is solved. I pulled codes on it and I got 103...mass air.....and 118 temperature sensor(did not replace that sensor yet). I replaced mass air and cleared codes and it is still there. Now codes 152,134 O2 sensors come up and it is running like crap. I cleaned the throttle body as I have read and seen video about...same result. Do I need to replace all the other things before I proceed with anything else. It has also been hard to start. Any help would be great. Thank you in advance!

A bad temp sensor and bad o2 sensor can make the car hard to start.

You may want to take the car and fill the tank with 91+ octane, add a bottle of Lucas fuel injector cleaner, replace the plugs if you have no proof that they were replaced recently as outlined in the owners manual, then take the car of a long drive down the highway, maybe 140 miles or so. 70 Miles, turn around and come back. Then see how the car is running.

To be honest with you, I'd rather purchase a car that has been driven daily with 250,000 miles on it than one that has been sitting for 2 years with 80,000 miles on it.

When was the timing belt last changed? If the answer is NEVER, you should have that done before starting the car again.

Timing belt was replaced before I started it. I am going to replace all the O2 sensors and temp sensor and see where we go from there.
