This is true...

I didn't think about that, but it is good advice.

I just disconnected my fuel pump fuse for 45 min.( i did not disconnect my battery).The code 43 still came up. I checked the air filter, fuel filter, coil, plug wires, hoses for cracks or holes. Everything came out fine. Something is fouling out my spark plugs and causing my code 43. If my cam gears are off by a degree would that give me a code 43 or a bad o2 sensor that is not regestering. If i replaced my EGR valve with that block kit would it help my idle problem. If any body can help with this pron\blem I would appriciate it.

Then it did not clear it from the memory. You may have to go to Autozone or someplace that has a reader and ask them to erase the code. Your cam gears should not be off unless you have changed them recently. The timing belt could be off, but then you would get a different code. The EGR blockoff kit may help your idle, but will also give you a Code 32 unless you have a Mopar PCM or AF/X PCM.

Try cleaning your TB with a sensor safe carbon cleaner. That may help your issue. Pull the plugs and see it they are still OK, they nay have gone bad on you already. Next thing, would be to replace your fuel injectors.
