I have been recently working on my car a bit. I had this stumble bad before i put it away for the winter. I put a new battery in the car it has lightend up but still there. I replace the egr valve car runs great! It went away a little more but its hard to tell if its still showing up. It seems after i rev it out a bit it seems to be gone. I was wondering if this might be carbon clearing itself out of the system due to the bad egr valve the i am pretty sure was cause a vacuum leak. I do notice tho when i am in a gear the that brings the engine down below 1500 rpm and i give it some gas there seems to be a skip.

 

if the plugs were fouled from carbon what kind of symtoms would i get. How hard is it to changed plugs with hooker shorties?

 

I changed my plugs after 3000 miles and my car went back to the way it was before. It had a serious power drop and was very hard to start and now its one blip of the key. My headers are better than stock so your should be similar. It takes me about 1 to 1 1/2 hours with a few breaks to let my hards rest from cramping. The right extentions and a stubby spark plug socket really helps.

 

The thing is ihave no power loss. The car is an animal, and i only have about 10,000 iridium plugs so i dunno.
