replace your spark plugs, before you try anything else. They go bad alot in the LXI.

my spark plugs r new and the wires are to!i got a question y does my right spark wire make a sound like when the car is on and when i hold it it stops is this good or bad it sound like something knocking!

its just loose, try clamp it on to the plug so it stays, dont clamp it hard though cause u would still wanna be able to take it off

Just do the regular tune up for the ignition, fuel and get a shop to get your valve lash adjusted to specs (unless you are brave and talented enough to do it on your own). Follow the maintanence schedule listed for our cars for the dictated milage, it should help you keep your car in tip top shape

follow the link on my sig and download the free shop manual. Its the best you could possibly do. I was at your state and before i even touched the car, i read thru the whole thing, understood what it meant and how things need to be done. then i used to look at mechanics work on cars and often hung around my mechanic's shop at either at his house or at the landRover dealership he worked at to see how they do things. it will eventually make sense to you.
