4-5 seconds after smooth initial acceleration to approx 4000 rpms engine suddenly drops 400 rpms lower then the initial setting
from idle set to 4000 drops to 3600 after 5 seconds
from idle set to 4500 drops to 4100 after 5 seconds
can stiil obtain WOT
never looses 400 rpm again until after return to idle
then repeats loss after initial high rpm setting
i would appreciate any suggestions or ideas
thank you
