Hi guys just got towed home was going well downhill,reached about 180km, when i started going uphill power was totally gone.carried on for about 7 kms got out of the moterway Swithed of car put it working again did this a few times still the same Now the car has no power(does not go over 60km)and plenty of smoke on acceleration.No warning lights and auto gearbox seems to work properly,due to loss of power it goes down to 2 or 3 on any sort of hill. What do you think went wrong car is now on 150 000 kms.
