Revs hunt when idle
Posted: Sat Sep 12, 2020 7:27 pm
I have started having a problem with my Bongo 2001 automatic petrol.
Sometimes when I am stopped at a temporary traffic light or waiting to pull out from a petrol station. That is in drive(automatic), foot on brake, the revs suddenly dip the go back to where they were at least twice in a row. I think they say the revs are hunting.
I also get this when I am turning on a roundabout or/and just accelerating off the roundabout. I am not sure if it is hunting but foot hard down seems to sort it out eventually. It feels like fuel problem or a sensor messing up the engine mapping.
Someone suggested a faulty MAF sensor. Seems to only happen from low revs. Okay when above 30mph.
Any ideas?
