My 1991 Prelude at a 100kph is reving at @3000 rpm (on the flat) push down
a little to go up a slight rise and it drops down @200 rpm (lock up I,d
say)and stays there till I lift off the thottle a little.
Then it goes back to @ 3000 rpm it will repeat this over and over.
Other than this hiccup the auto is prefect apart from a jumpimg
up(hunting) and down gears as I coast down hills at @50 kph
I have just changed the oil (life unknown) the car has 166,000 km on the
clock.
The oil was black and a burnt smell.
Any Idea's, the auto shop's don't.
Is it thottle control cable rigging?
