Hey there, just bought a used 2010 XPro the other week with 90k. I had a buddy with a shop check it over and I too have the pesky knock sensor code stored with no CEL. I read its a common problem but its pretty 50-50 on whether or not to fix it. Its got 90k and I don't know much the history except one owner policeman who traded for a jag. I imagine they may have had kids or did stake-outs because they opted for the DVD player.
So my question is, after I clear the code and see if it comes back, how successful is cleaning the MAF for the issue? And will I feel any drivability issues or run into domino affects if I don't replace it anytime soon? Its a part time driver for fun and for storm duty at work.
