500 is wrong! dead wrong, why? . (assumes 500 is real) hot or cold.
that means the ECU can not control idle. the ECU is hard coded to 800, it opens the ISC to raise 500 to 800 RPM in servo loop actions. and holds it there like a rock ,even in DRIVE ! (my guess, is duty cycle set wrong. bleed screw turned 100% CW [closed]
can do that.)
that is right a hot engine can run great with too low of an idle speed, the 800 is EPA dictated, and hard coded, so smog is lowest at that RPM, and CAT lasts the longest (that is 8 year warranty on that part alone) and the trottle reponse is way better at 800 , after all 1/2 the equation for HP is RPM.

simple alegbra.... see how RPM works? rpm x torque see that relationship?
the pedal feels heavy (as in just the pedal) or the pedals demand for power , is weak or slow. (actual throttle action gives weak engine power ?)
if this is a power, issue why not get idle RPM fixed. so HP is there ready to use.
its hard to diagnose any car on earth, deaf blind and not present.. for sure...
even videos dont help cant see drivers feet or road conditions, etc.
the stock HP at idle is about 15hp. at 800. so if you lower that, much, the HP rolls off fast.. (not to mention supper low air flows, cause the maf to read wrong..
the power at lower rpm is very pathetic.
so needs aggressive right throttle foot action to bet more more power, 300 more rpm more power.
so.
i have only one question why is the ISC dead. ?
