Oh, btw .. a little more info: I'm poor.

"assuming everything is working correctly." . That's precisely the prob. For instance, in my case the next suspected problem causing richness is the speed sensor. Well I can test resistance but don't have an oscilloscope to see if it truly works. I do have another speed sensor though, but if i replace I want to confirm that it actually made the difference between allowing the car to run at stoich vs. open loop rich.

So there's no trick. I was hoping there was quick test to see if its even trying to run at lambda (I imagined it'd go something like this:
let car idle or have friend hold at 3K -->unplug the [whatever sensor...probably oxygen sensor].

Did is affect rpms/smoothness? If yes, then it was running closed loop; If no, then it wasn't running closed loop.
