My LS400 is not running like a V8 should. For the first few years i've had the car it ran great. I use to fool around and drive fast, and when i hit the gas it picked up speed and roared like a V8 should, now it doesn't pick up the speed nor rev up like it used to. What could be the problem? What do i need to fix?

Any lights on the dash kit up? How many miles on the car? Change any parts lately?

Any lights on the dash kit up? How many miles on the car? Change any parts lately? No check engine light. 134590 miles. And a few months ago I changed out the alternator, PS pump and line because I have multiple ps leaks. A week ago I changed out the gasket valve covers. Today I changed the air filter. And about six months ago I had a tune up done. Didn't change the distributor cap or spark plug wires. I'm going to do those soon as well as a throttle body cleaning.
