I have 00 camaro nothing special V6 3.8 liter i currently have 93,000 miles when is the best time to do a tune up on these camaro wat is the certain mileage?

 

You're over due. 100,000 mile spark plugs...no such thing. The manufacturers just want your car to start to run like **** so you take it in to them so they can hose you on other things.

Change the spark plugs
air filter
fuel filter, after you run an entire can of Sea Foam through 3/4 of a tank of gas
flush your radiator
get a scan to make sure other things are working as they should be (ie: 02 sensors) maybe spark plugs wires but usually they're just fine
do a top end cleaning, Sea Foam or Mopar Combustion Chamber Cleaner
