I have a 2000 RX 300 which has been doing very fine until yesterday. I was
coasting at about 110km pH when suddenly, the car lost power. It revs on id
le but will not accelerate when on the go. I have had the fuel pump changed
but to no avail. There is this constant hissing sound coming from the engi
ne area as if there is an air leak.
Any one know what the problem could be? Thanks in anticipation.
