850R throwing codes like candy!
Hi all... So i will start by saying that the wagon runs totally normal. No symptoms of anything. ( my wife drives it like my grandma would) But I happened to go run the codes again from a CEL that threw a while back... ( I knew what it was so i just kinda ignored it)
The First code was as expected since it registered this about a year ago... P0133, 02 sensor Circuit slow Response.
The new ones that surprised me were the myriad misfires: P1310 /P0303 / P0300
Regarding the 02 code, I read this info and will be following up on it:
"A code P0133 may mean that one or more of the following has happened:
The oxygen sensor is faulty
The wiring to the sensor is broken / frayed
There is an exhaust leak
Possible Solutions
The simplest thing to do is to reset the code and see if it comes back. If the code comes back, the problem is more than likely the front Bank 1 oxygen sensor. You will likely wind up replacing it but you should also consider these possible solutions:
Check and fix any exhaust leaks
Check for wiring problems (shorted, frayed wires)
Check the frequency and amplitude of the oxygen sensor (advanced) Check for a deteriorating / contaminated oxygen sensor, replace if necessary
Check for inlet air leaks
Check the MAF sensor for proper operation""
That said, ill do my diligence and check in, but just wondering of anyone thinks these could be linked at all. Best case scenario is that its time for a good old wire/cap/rotor/plug tune up!

How old is the sensor? If older than 100,000 miles, just replace it. It will likely gain you at least 1 mpg, which will add up quick at these gas prices.
The misfire is another situation.

the misfires codes
I have a 95 turbo. I got vacuum leak (0p0171) and misfires p0302,p0304 and random misfires~3 codes related.
I just change out the spark plugs, wires,cap, distributor. I payed alot
for 0EM spark plugs pack($75 at the stealership) . These were specially made for the volvo 850 turbo. i previously put aftermarket plugs about 6 months and the codes came up soon. With the official volvo ones, All the codes went away! The plugs cost as much as the other 3 items(Bosch wires and cap and BMX (generic)distributor.
No misfires since.
