i have a 1jz with a single turbo running 880cc injectors and a power fc. and all the supporting mods. fuel pump, fpr, etc..
With my TPS plugged in, my cars idle will bounce from 800 to 1500 rpm most times i stop. But i found that it happens even if it let off the gas while driving and press the clutch in. it will just bounce around.
so i unplug the tps. has a bit of a higher idle but no bounciness at all. i tried to adjust the tps within the specs but i can't. i can only get it to read 3.6k ohms at the lowest and 3.9 k ohms at the highest, while performing the resistance test.
is my tps no good?
Then i thought of the idea to have the tps plugged in, wait for the idle to go bouncy and then adjust the tps till it didn't bounce anymore. this worked, for the first 3-4 hours of driving, then it came back.
Right now im running with no TPS sensor. i feel like its affecting my MPG.
but i would like to get this sorted out. any help is appreciated. I've searched like crazy
does the ISCV affect it? i had a mini filter on it before, then someone told me my iscv was no good and to just cap it off and open the throttle plate a little more to create a controlled vacuum leak. Maybe this is affecting it?
