I have a 2000 s70 glt-se with 115,000 miles. recently the check engine light came on. after a few drive cycles, it went off. then a few drive cycles later it came back on again. this has been going on for the last month or so. i had it scanned and the code is P1171. had the light reset. couple of days later it was back on again. any ideas?

 

You might have a vacuum leak.

 

code is po107
