full power loss is NOT The TPS SENSOR. THE TPS DOES NOT LIMIT WHAT THE MAP DEMANDS, THE MAP MUST WIN? SEE?
it's map (MY GUESS)
the map must read correctly or there will be no power on any G engine TBI
shortest list: Possible your case.
1engine good, CAT gone. so engine will breath 100% and pump air 100%, cylinder compression at 150+psi min, that's 10bar.!
2: good spark, and must advance past 30 degrees, at high RPM or power will be lost , huge loss of power,
2a; all 4 cylinders good spark. (when power loss happens is there felt/heard misfiring?)
3: map most function correctly or the ECU can not match fuel to air, and goes lean and bogs,
4: fuel pressure is ok,sure, but injector must not be clogged, or its Screens.
there are simple test for each
using simple tools gauges, and a DMM meter.
the above is the correct order,
good luck
and cheers.
