[QUOTE="efnfast, post: 17030087, member: 104733"] My handheld and SCT and HP Tuners all say no codes (and no check engine light). I would periodically get a code though when it's like -40*C outside and I lug the engine .... I think the STFT would go up for a split second to like +20 (normally around +/- 5) and since the LTFT would be sitting around +20-25 that then caused the code (i.e., the code needs around +40-50 combined to set) I really don't want to pull the intake (I've got a hundred projects on the go and because of its age every project on this car grows exponentially in time and it's my daily driver) .... but everything is signalling vacuum leak to me, except it idles fine. I would think if a vacuum leak is enough to cause +20-25 at idle then idle would show some signs of suffering [/QUOTE]
