that vid. is set to private, so link fails.
shivers. (is this in neutral?)
hot or cold engine or both.
is RPM hot 800 , plus or minus , 50 RPM?
does RPM hunt , at any time hot?
is shivers, RPM variance< or a sound only, ?
this car has automatic, IDLE controls. and will hold idle tightly, hot.
one test hot is thrown on A/C , blower to high then, head lights then rear defroster. at once to see if RPM goes way low. (and sticks too low ,or takes 1 second to recover)
it must hold 800 hot. if not the ISC system is failing. (that dont mean its bad, just that it can't handle some problem with air or fuel,etc)
the idle will not work if the Idle switch in the TPS is bad or set wrong.(calibration)
a voltage test at the TPS solves that riddle. fast. backprobed.
if the shiver is sound only, not RPM surge, its most likely the tins, near the CAT making noise, or loose exhaust manifold shields. or something else loose but is not normal.
