CPI gone bad?

CPI gone bad?
have been trying to diag. this idle problem i have been having for a while now. I will first start off with what i have done. 1. I have replaced the fuel pressure regulator as i found that the passenger side of the lower intake was washed out, but did not fix the idle issue. 2. Cleaned and installed screened gasket on egr valve, still same issue. 3. Replaced fue pump and filter, still no fix. 4. Replaced distributor cap and rotor, still same ruff idle. Ohh and the plugs and wires are new within the past couple of weeks. So I was out driving the truck around and then took it home for it to cool off so i could pull the plugs and inspect them. I pulled the pugs and found that everyone of them was wet and smelled somwhat like fuel. I cleaned them off and reinstalled them and it ran well for about 30 seconds and them it started running rough again. It only runs rough at idle but the problem i am having is I have no black smoke or any smell of fuel for that matter. Do you guys just think my injector is leaking? What else could it be? I have checked the spark with one of those testers and it seems good, very bright. I ordered a new cpi and supply and return lines do you guys think that will repair it? The truck still has tons of power while accelerating.

You should still put new Ac plugs in her after you replace the spider, make sure you clean the EGR port when you have it apart.
