Engine light came on last night and took my 01' Volvo C70 2.3 litre turbo up to Autozone to read the code and it is getting a p1171 code. Any common thoughts on this problem? I heard that the MAF is usually the cause and to buy a spray and try to take it off and clean it first?? Just want to make sure here... Funny but the car still runs great though.

 

Make sure you have no vacuum leaks as well.
