Tried to search low idle speed issues, can't find anything related to my problem. 1998 A4 with V6 non turbo, idles at 500rpm and will stall off and on. I am getting a code for low idle , is there any way to get it up to 700 or so? Would the MAF be a source to check? I have cleaned the TB and check vacum, it is at 17in. Thanks for any help.
