A combination of dropping RPM and sluggish acceleration at the same time points to a more specific set of causes than either symptom occurring on its own.
What Ties Them Together
Restricted fuel delivery, a failing supercharger clutch or the ECU pulling back power due to a sensor fault can all produce this combined symptom pattern.
Narrowing It Down
Checking live RPM, fuel trim and boost data together with the M-JET DIAGNOSTIC tool makes it much easier to see which of these systems is actually behind the symptom.
