I did a power contribution test on a 14 hour cold soak.
#3 and #7 start out low and come inline once the truck warms up. #7 is the lowest of the two.
#8 starts out high and drops out as it warms up.
After some reading, I am wondering if #3 is bad or not. I know #7 needs replaced, but not sure about #3. I read that if you have a bad injector, it could give a false reading on the injector right before and right after it.
Can you post a pic of the screen while its un-compensated?
Like this.
Yes a cylinder before may compensate for a dead cylinder in front of it in the firing order. Like in the one above #2 was high because 7 was low. In this case 3 & 7 was replaced and now are all even.
