My son is driving a '95 3.8ltr concorde and it takes off on its own when he is just cruizing down the road. I drove it the other day and just idleing down the road i could feel it surge then stop the surge and stop etc. Someone said throttle position sensor. Is there any way to know for sure??? Or PCV valve??
I just talked to him and he says it doesn't accellerateeither sometimes whenhe is pressing on the gas. Any ideas??
