Help Needed: Sluggish W124 260E Revisited.
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.
