I have a 1997 E350 w/6.8 triton. The Exhaust Cat and muffler gets red hot. I replaced the cat as it colapsed inside as did the muffler. I found on other vehicles if the "y' pipe is red hot, the engine is running too lean. In this application the inside of the exhaust is black(Rich?). The engine is sluggish and idles rough. Could this be a fuel pump problem?

Check the timing, check that nothing is blocking the tailpipe. Clean and reinstall the spark plugs. If all OK here check fuel pressure with mechanical fuel pressure gauge.

The OBD said there was one missfire. I changed the plug an coil. I plan on changing all the plugs. I wonder if low fuel pressure woukld be the problem? I would think the pump is bad or possibly the fuel pressure regulator?

I've finally gotten back to the V10 plug issue. Well, the plug isn't broken after all (I Think). I thought it was stripped, but I started it because nothing seemed to work getting it out. It appears the Hex is stripped. I've never seen that happen. I still plan on changing out the fuel pump. I'll go from there. It won't stay running, as if it loses fuel pressure. I have no clue how to got that plug out easily. If it was stripped, it should have blown out of the head, but it didn't.
