Sup yall
question,
my buddy's 96 svt stumbles under hard acceleration, no check engine light like i said.
hooked a scanner up to it today and monitored data as we drove, when it stumbled:
TPS 93.3%
Load 98%
all 02's at about .850 mv
s/t fuel trims at about 11-14
fuel system 1 goes into open loop
then when you let off,
TPS 20%
Load 23%
all 02's go to 0.000 for about 5 sec
s/t fuel trims -3
goes back into closed loop
weird thing is TPS never goes below 20% even when fully off throttle and the load calculation never goes below 23% and when rolling into it goes right to 80%
Are these things known for bad throttle position sensors?
Any ideas?
