Hi all, my 2011 prado, automatic, has a very annoying habit of surging/ pulsing while under light to moderate acceleration. This occurs at around 2200 to 2300 rpm and It will occur whether the transmission is in full auto or S.
At certain levels of acceleration it is quite violent (as if moving accelerator pedal from 0 to 100% rapidly).
It also occurs with cruise control engaged as the engine approaches 2200 rpm and will continue surging lightly until rpm passes approx 2400.
Fuel filters and air filter are new.
Has anybody had a similar experience or know of others who have, and what the cause may be?
Cheers, Steve
