Getting code P0303

[SkunkApe]

Hello all,

New member here. I am getting code P0303 and am wondering if there are any reliable quick fixes. I have a 2006 LJ Rubicon and I've seen some posts about using the heat wrap for the fuel rail and injectors but all of the ones I've seen are for years up to 2004. Can I still use this and does anyone have any experience about this being a good option? I appreciate any help that comes my way.

If it only happens when conditions are hot I'd sure give the insulation wrap around the #3 injector. You have seen the link to the insulation specified by the TSB right?

The one's I've seen look like they're all for models up to 2004. Can I still use this since I have a 2006?

Absolutely, the 2006 has the same fuel injectors.

Ok. Good to know. I just placed the order. Thanks for the help.

When I got my PO303 code it turned out to be a bad spark plug. I also replaced all the heat shield because it was looking ratty and added the fuel rail and injector shielding.
