Drive home this morning SUCKED
I have been having this issue lately with my AFR's going CRAZY. Like 1 second it's 10:1 and the next it's up near 16. Last week the car ran pretty lean, then week it runs really rich. WTF. I made no changes and uploaded nothing to the MS. This all started happening on it's own. My idle suck too, it idles very lean and it idles high. Last week it idled at liek 1300RPM, today it's up near 1600. I uploaded my .msq and a log and am hoping that a guru could take a look and tell me it something simple like a vacuum leak...thanks.loaded.msq

My LC-1 is on 0-5v for the MS, so you know. I have been running the car for many months and have never had an issue like this. I haven't even been getting OBD codes, but now I have 3 codes, lean, rich, and idle high...I think they are P0171, P0172, and P0507?

My temps are dead on. I even checked it with an infared thermometer for proper calibration. Like I mentioned, it ran fine like this for quite some time, and now it runs like ****.
