I have a pending fault P219A code. I installed the OBDII Diablo Sprint AFM module on my rig around October 10th or so. This morning I get some missing/misfire as I'm driving, around 1200 rpms mark or so. I've been using 91 fuel with this Sprint module until last night when I put in some 87. I got to thinking maybe the tune configuration of that module doesn't like the 87 so I added like some 91 this morning, and drove on to work.
I actually decided to unplugg the module, drove on home with no missing/misfire issues (I couldn't seem to recreate the problem) and plugged in my reader which gave me the pending fault P219A code.
This is a 2011 Yukon 5.3 with about 165,000 miles.... It's probably time to replace O2 sensors anyways, hasn't been done as far as I know- 2nd owner here.
I know I need to check for some vac leaks, but just wondering what has been some fixes for this.
Thanks!!
