TPS, Fuel Pressure, but I had simular power vacumn at 3500-4000 experience with a mal-adjusted MPS... ECU gone haywire??

Does it sputer at 4000rpm underload only or will it do the same sitting in the driveway in nuetral..?? That would be a tell..

The TPS does not care about vaccum..

Mps issue: part load..

Failed aneroid cell: Causes the car to run rich at idle, with poor part-load response.


Maladjustment: Many owners and mechanics have tried to adjust the sensor by removing the epoxy-covered "plug" and turning the adjustment screw inside - this often results in unpredictable behavior
