It seems from a stand still to be mostly ok, it’s applying throttle while moving - I have to depress almost a full inch before I get throttle response. So annoying!
Someone’s got to know what’s going on. I have a sneaking suspicion that the downstream sensor does have something to do with AFR or sending back info to ecu on air flow to adjust throttle, etc.

unless you're throwing engine codes it's highly doubtful that any close-loop feedback from the downstream sensor is causing what you're experiencing.
When you say you had the mechanic change the up-stream sensor while working on curing this issue originally.... is that replacement sensor still in there..?
ps: Like I mentioned in the other thread.. I've been running this work-around for over the past year with no CEL or change in throttle/performance, etc. This being a very common solution would probably have resulted in regular feedback from other if this was related to the downstream o2 sensor spacing... just my thought..
