Does anybody have a good link to these two answers from the FAQ Sticky?

My car idles low, high, or not at all. What should I do?
-First thing to do would be to clean the Idle Air Control (IAC) valve. There is a how to here: http://s40concepts.net/forum/index.p...b1bce0b4860f8f
While you're at it, you can clean the mass airflow sensor (MAF.) There is a how to here: http://s40concepts.net/forum/index.p...b1bce0b4860f8f
Both sensors are very easy to clean and are a great first step towards diagnosis.

The links are dead and don't go anywhere. I'm having P0171 and P0236 and need to clean my MAF to see if that corrects the problem.

 

I just bought the maf sensor cleaner made by CRC from FCP and follow the directions on the can. took about 15 minutes total. It is just a spray on, let evaporate, re-assemble deal.

 

Volvos rock, do you have a link for that? Thanks

 

Go down to like Autozone/Pepboys and buy a can, they are like 5 dollars.

 

sorry, not very computer literate, but go to FCP.com or IPD.com and serch for maf cleaner. and like showtek said most parts stores as well.
