Hi Guys, I'm having P0101 Issues on My 2006 XC70. Seems to be throwing P0101 Codes. I've tried to clean the Mass Air Flow but problem persists.
Now On Occasion Car Has rough starts and looks like it wants to die at start up.
Iv pulled out the Freeze Frames for a Couple of incidence of the DTC. Any Ideas?

I Don't want to debug by replacing the MAF as the part costs about 400$ . So I might start off by replacing Spark plugs and moving onwards from there.
