I found injector wiring harness burned at intermediate connection and replaced from injector connection to intermediate connection (not PCM), still showing P0206 code.
When I removed the MAP sensor to check with hand vacuum pump, (pumping down MAP sensor past 10Hg, causes engine to die) the RPM increased immediately, when I plug this opening, it shuts off. Is it running rich?
Restarting here are the readings:
Short trim fuel B-1 = 0.0%
short trim fuel B-1, S1= -25%
short trim fuel B-1, S2 99.2%
CO2 B-1, S1=0.645V
CO2 B-1, S2= 0.470V
RPM 1300-1425
Absolute throttle =13.7%
MAP (off plenum) 29.7 Hg (code reader reading) (opening unobstructed)
vacuum reading on plenum= 8. Hg (open MAP location opening unobstructed)
What do you think this could be?
I appreciate any help you can give me.
