Threw a CEL last night, haven't driven her too much since I put the TMIC on it. My LTFTs are still around 12 (MSCAI), but my AFRs are looking good, so the ECU is doing a good job compensating (actually running rich, 9.x at WOT). The CEL coded out as P0401, exhaust gas recirculation flow insufficient detected (why does the AP talk like Yoda?) Just prior to the CEL I was seeing a lot of KR (4.x) at partial throttle. The CEL cleared and didn't return but I only drove it about 2 miles after that.
So, not sure about the KR, but my plan of action is to finally do the logging that I need to do to calibrate the MAF and see if things don't improve.
