3.8L engines are good running motors. Plug wires and plugs can become an issue never clean a plug and reinstall with new ones. Don't replace wires with used wires sounds strange but people try to save money on parts only to spend more in the end.

Excellent addition to this thread!

Hi Ken, I have a 2008 Chrysler Town and country 3.8. after changing cylinder plug and wire on 4 I still get heavy vibration from my engine at startup.

So I changed all wires and plugs. To find out the the engine was doing the same thing.

Hi,

A cylinder misfire can be caused by a couple of things. How many miles are n the vehicle? Also, are there any noises from the engine? Are there any odd smells or smoke from the exhaust?

Let us know.

got 2014 town and country my code is Po303 I've changed all plugs still have a code P0303. what to do next? thank you

Hi,

If the misfire is still present at cylinder 3, switch the cylinder three coil pack with a different one on the engine. If the coil pack is bad, the misfire will move to a different cylinder.

For example, if you switch the coil packs on cylinders 3 and 4, if it is bad, you will get a P0304 and the P0303 will go away,

Let me know.

Joe
