Hey Everyone what do you think?
I have a 1998 s70 with about 132,000 Miles. One day I was going to pick up a new cell phone and all hell broke loose. I was getting on the freeway and I stepped on the gas hard (close to red line.) After that my light engine light came on and car started running very poorly. When I am at a idle it runs very ruff, has the bad shakes. It does not have the power it used to, when cruise control is on it fluctuates about 5 mph on every hill. I brought it to my local autozone and they said the code was a po301. Which could be anything from, bad plugs, bad plug wires, vacuum leak, injector fault, high or low oil pressure. If you have heard anything like this let me know. Thanks guys!

 

If it has not had a tune up lately thats where I would start.
