91 rough idle, won't rev

Got it solved. Turned out to be a cracked plug. All good now!

Or so I thought. It's back with a vengeance. Now restarting doesn't always fix it. It bogs down if given more than 1/4 throttle and starts bucking really bad. I'll be digging into it here soon.

I unplugged the MAF and it felt like I gained 50hp! Unfortunately the idle was horrible and it got about 8mpg. Threw a used MAF off a junker on it and all is well.

The bottom half of my airbox is warped and the filter doesn't seat correctly, I think dirty air is getting past and killing the MAF. I'll be picking up a new box at the yard soon.
