Update: still not wanting to spend all that money to have it scanned, but have noticed something new. When in limp mode, MAF connected of course, I get a rough idle. Never when in open loop. So, it has to be a sensor that is not used in open loop, that would give a SLIGHT bouncing idle. It gets worse and worse subtly when I do notice the idle is bouncing.
Someone? It can't be that expensive to fix, so I don't want to spend 100 bucks scanning it, when the sensor will most likely cost less than that to replace.
