the ect must be like 300 ohms hot, 180f, is that,
pull connector hot read sensor with any ohm/dmm meter made
the TPS must work , this signals the ECU that you tipped in the throttle fast and prevents TIp in bog.
the the MAF wakes up (air flow is slow and delayed) and the ECU goes to enrich mode at tip in via TPS early warnings.
also if the idle switch opens late the ecu does not see the tip-in until too late and bogs (hesitates)
this stumble is this hot or cold engine or both?
