Well, wouldn't you know...

Top down ride home from work, 65 degrees and clear blue sky, and I look down and see the CEL on! Got home and pulled a P1128 code, which is an enrichment limit code for cylinders 1 - 3. Like the sig says, 2000 S, no mods, stock air filter, 52k miles.

So here's my thinking... no 1130 code, so it's just one side right now, so it's probably not something that both sides have in common. There's no smoke at startup, so AOS is likely ruled out. MAF, fuel delivery, or vacuum leak problems should kick both sides, so they are out. Pretty much leaves O2 sensors. Or course, I guess that given a few more drives 1130 could pop and then this is all out the window.

Other possibilities or opinions? Anything is welcome, Thanks!
