Rod hitting...
Ok, I unplugged MAF, and again, myflashing CEL goes away.
THEN, I rev it up.
It is ROUGH, kinda grinding ish noise?, and the lights(dash, interior, headlights, all) get brighter...I take foot off gas, and RPMs shoot down to below 1000, the lights dim, rpms then smooth out to the typical 1000 and normal lights.
Do the lights dimming and such have any hint for my problem, or is this just typical? lol..
(This is all I can do right now is little steps at a time, thanks to work and some other crap I got going on.. :/ )

Plug pics will come tomorrow, but honestly, they all look pretty normal!! One is a LITTLE whiter, but not ash deposits, and not as white as the "hot" plug on the picture.
I'll have to make a video of this sound and see if you guys can determine something, but I might have to take it to a shop.
When I turn it off, there'* almost like I hear a vaccuum leak, a rush of air, but I might be hearing things? idk.

You should hear no hissing when you shut the engine off. If you do then there is a vacuum leak. Check between the upper and lower manifolds. I had one that carb cleaner didn't really change the RPM. But I was able to see the liquid being sucked in. use more then just your ears, you need to use your eyes as well.
There are moments where it shudders REALLY BAD when I'm on the throttle at 45, 50 mph. I let off and it coasts just fine, no shudder. Give a little gas, starts to shudder, won't go above 1500, 2000 rpms, but sometimes magically jumps out of its funk and stops shuddering.

Kind of sounds like a blown intake gasket. My engine had that same problem, found I had a blown gasket between the supercharger and the intercooler plate under the snout.
