Australian Car Repair Issues? Ask an Auto Mechanic for Answers ASAP
I am sorry that you have not been helped yet. I just came online and saw your question.
Ok, this could be in the throttle response such as the app sensor, tp sensor or may be transmission related, but I need some more infomation such as whether it revs fine in park, what the top speed is right now and the rpms at the speed, and as much detail as you can provide.
