the idle speed ever drop lower that 800 rpm hot? or near stall, and engine shakes?
if yes, it will be a sticking EGR.
if not that, that hope sounds to me like
1: TPS bad
2: TPS not calibrated right.
is this a auto or stick shift.?
the tps cal should be . at .016" inches. (0.40 mm)
that RPM drop, sounds like the ISC is sticking, like the EGR both need cleaning from time to time.
but that HOP, deal , is TPS like, to me.
if the TPS, is set too open too late, it will do that. (in fact the idle controls will fight the drivers advancing right toe) and ugly effect this is.
i do not have a Santana book, so must assume the .026" calibration is the same.
and is done with the dash pot defeated.
