[QUOTE="Gringo185, post: 14067086, member: 42351"] I hooked my 2014 Focus ST up to the IDS the other day and decided to poke around a bit (pull codes, check out fuel trims, etc). While I was browsing around, I noticed that my LTFT was at a +7% (STFT was steady at 0%). I wasn't sure if the recent AutoX had anything to do with it (, so I reset the KAM and immediately checked it again. LTFT was reset to 0%, but STFT was already at +4% and climbing. It runs and idles fine. Have any of you heard of issues with any premature fuel system obstructions that could be causing a lean condition? It has less than 8k miles on it and I've AutoX'd it twice. I didn't see nay TSBs related to decreased fuel economy, fuel trim issues or anything else related. I pulled codes and the only thing that has come up (twice now) is "P26DE: Engine Sound Control Circuit Performance". The sound symposer checked out fine, I cleared the codes, drove it for the day and it popped back up. I'd appreciate any info or advice. Thanks in advance. [/QUOTE]
