We have a problem.

The Problem: Sluggish acceleration until past 4,000 rpm when power kicks in real hard.

What have been done so far:

1. Replaced fuel divider (symptom persisted);
2. Emptied fuel tank and cleaned fuel lines (some dirt uncovered);
3. Replaced fuel pump and filter;
4. Checked coolant temp. sensor.

The result: Nothing significant.

Here is where we need your possible causes to look for ....
