85%? That's approximately the setting for the square trans connector. What about testing and setting it off the flat 3 wire connector at 17% of input voltage?

Its your o2 sensor. Mine did the same thing, everytime I would press in the clutch to stop it would die or almost die.

On the thing you gave it said needs to be 83% of what you first tested and then 17 percent on the other prom connector of what you first tested. When I can get the first 1 was 85 percent of what I first tested and then the second prongconnector was 15 percent

Needed another new tps and retune it and a new pcm! Now it runs amazing no stutter, no bad idle and no bad hiccup !! Drove a 14 hr. roundtrip and 900 miles no issue!
