Hey guys, I've had my 2000 XJ for quite a while now, 4 years and almost 50k miles. Its always been down on power compared to other XJ's. I put on a Spectre cowl intake, full 2.5 exhaust, 2.5 High Flow cat, 62mm throttle body, injectors, as well as doing plugs to make sure there's no issues. While this helped a bit, its still a dog. A friends 99 on stock 3.55 gearing and 33's has more power. Where would you start looking to help it pick up some power? About once a year it pulls a code for an O2 sensor then goes away. Thanks for any help!
