Thanks for the reply's. The timing chain and the cat could both be culprits. I use mobile 1 and change the oil every 5k miles. I just replaced the spark plugs about 5k miles ago. I thought that might have been the problem, but it only helped a little. I just miss the days of being able to punch the throttle at 70 and take off. It still does well, but its like Im losing a little power on the top end, feels like im missing somthing in the 4k to 5k range on the tach.
