I have a 2007 chryslet pt I do not have a manual am I correct that at 40ooo miles I need to change the spark plugs?
every 36K unless it has platinum then I do those every 60K, dont forget to replace the upper intake gasket when you do them and new wires are always a good idea at the same time. Use champion plugs also.
If you don't have a manual, I'd suggest picking up a Chilton Manual at your local auto parts store... not only will it have most of the information from the original manual, it will help you in doing a lot of simple repairs to your car that can save you lots of money.
