Rpm droop flashing on/off on diacom 7.4 mpi
7.4 MPI (310 hp)
NO fault codes stored on the ECU but when running on idle speed diacom screen (right side page) flashes/varies on the line "RPM DROOP" ON & OFF all the time when engine running faster (+1000 rpm) "RPM DROOP" stays on OFF why @ idle ? What does rpm droop means? How to solve this issue? |
Your idle is falling below preset minimum. Not knowing a serial number or year it is probably 600, so its falling below
Look at the IAC and what are the counts and is it steady? |

Have you checked base timing against what your repair manual says it should be?
