My 300D is suffering from an apparent lack of fuel at 2900 rpm+. The car starts, runs and drives just fine, shifts well etc. but just when it should be starting to get some serious boost, (~2900-3000 rpm), it stops accelerating and just flattens out.
I have changed main and inline fuel filters. Additionally, I cleaned out the banjo nut and lines on the back of the intake manifold and the pressure switch (both were plugged).
What am I missing? Many thank for the insights.
