I have a 2001 V-6 - 3.8, lately my car has been I think they called it precubistion(don't know how to spell it)?? I changed spark plugs and the noise stopped for about two weeks and now it's back again. I'm also losing power and my gas milage is really getting bad. I know nothing about cars and don't really know what to do, can someone please help me???

I have 67000 miles and I'm sorry I have no idea what mods or stock is I know nothing about a car. I just know someone said it keeps spark knocking, what ever that is. I can't keep changing spark plugs every two or three weeks I need to know what is wrong with it!!

Does it still have warranty?

Any codes?

Sometimes if it is an emissions failure you still have warranty into the 70,000 mile range. Definitely get a scan done of the engine systems.

Another thing is to try and buy a higher grade gas on your next fill up. From a different supplier than what you are using now.

Good luck,
