I have 98,900 miles on my car as well as the motor. The car does not burn oil. One day I noticed the car not running as well as it used to. It has a harder time to get to 5000 rpm now and it just doesnt have that torquie feeling like it used to when it was stock at 50,000 miles or so. I was thinking it might be the timing chain that had stetched over the miles. If I go to change my timing chain will I need to drop the oil pan too, or is the one piece pan gasket standard on a 95 gt. Does this even sound like what is wrong with my car. Someone help because I want the power back.
