So after hours of tinkering, i find that the wire loom that goes to the ECM had been sitting on top of the burning hot exhaust manifold and began to melt. Therefore, melting the small vacuum line that goes to what i believe is the MAP sensor which sits right on top of the passenger wheel well. There was only a small hole in the line but enough so that when i hooked my vacuum gauge up it read "0". When it was running and i put my finger on the hole, the rpm's began to go higher and the gauge went up to 17. I read in my Haynes manual that its suppose to get only 10PSI? Is this an issue to be getting almost double the pressure? And also, the check engine light stopped coming on after i fixed this and the ECM read no error codes. Hopefully when i get a whole new hose the car will run perfect because it still bogs down a little but not half as bad as it did.

Yes, that piece you show there is indeed the MAP sensor.

Also, vacuum isn't measured in PSI, it's measured in In/Hg (inches of mercury). 17 In/Hg is pretty standard and if you are getting that at idle, congratulations. You've sealed all of the vacuum leaks.

Ok yeah i could have sworn it was measured in inches but i wasn't sure. Hopefully it'll be running like new once i replace the line(s).
