Here's whats happening now:
1. Pulled plugs and #2,#5 and #6 were black from carbon fouling. Others looked fine. They were replaced less that 1200 miles ago. The black tips are an indication of plugs not firing correctly and possibly a rich condition.
2. Idle is rough! Definite gas smell from exaust. Sounds like a diesel. Could be plugs misfiring.
Things I have done to this point:
1. AIC - replaced gasket and cleaned with brake cleaner.
2. EGR - looks ok, replaced gasket. Will test tonight to see if I can make vacuum work on it.
3. Vacuum leaks, can't find one anywhere! Hoses look good. Fitings all snap good.Try carb cleaner at the bas of thr lower intake.There are o-ring seals there and they shrink with age.
4. Replaced upper manifold gaskets.
5. Pulled both after 02 sensors to look for damage. None noted.
6. Pulled first muffler after 3rd CAT to look for debris. Not a thing in it.Thats because the material can't get by it Then seperated Cat from flex pipe and looked in front. Clean screen and no debris.
Try running engine with rear cat separated from flex pipe.
7. Checked all COP's for 12v. Tested both "hot and ground" for open and none noted. All tested 12v.
You need to check resistance for primary and secondary windings of coils.
8. Tested all injectors for resistance in place. All were within the 11.3 - 11.5 Ohm range.
9. Pulled PCV valve and hose. Both looked good.
10. Had wife hide all flamable liquids as I am ready to douse this sucker and watch it burn! :mad5:Good idea
I see BogHog is here. Thanks for your help at the other site before it desinigrated and I lost what you suggested.
I can't get it running good enough to idle on its own without keeping some throttle on it. I keep wondering if its PCM, Injectors, COPS, or ? I think the CATS are still good as I don't have any debris in the system. Guess they could be plugged up, but would have figured to find something!
There is a TSB about 2005 tributes,escapes and mariners where wrong oem plugs will take out the coils and possibly the PCM.I don't have it off the top of my head but can get if if you need.Start with these few things and get back to me with results.P/S intake gasket set is about $8.00.
