21 doesn't seem like enough to throw afr off that bad. To check the exhaust side just duck tape your air hose into the tailpipe and then same procedure as intake manifold.

Are you showing any misfire counters or anything? Mine doesn't hardly ever but it's a thought since misses or a dead hole will swing afr to the lean side and I've had my car run smooth as hell on 5 cylinders and the only way I could tell was listening to the exhaust closely for a little chuff in between pulses.

The misfire counter is a mythical tool. I've wrote it off when I disconnected two plug wires and still didn't see a damn thing wrong on the scan gauge. lol
Sometimes it works, most times it doesn't. But if it actually shows somethin at all it's at least a good place to start. Otherwise I've gotten stage 5 ocd with mine and if it doesn't just purr like a sewing machine it's not right. Even a sporadic little twitch here and there and my day isn't gonna go well.
