Alright well heres the update, I hope I havent lost people's interest because I need you more than ever!

Replaced the plug wires with new, also did brand new AC o2 sensors and a new throttle body gasket. Car started right up like always and ran at 800 rpm (desired idle). I took it out for a ride and it did seem noticeably better than before, however still has SES light (code 33 low MAP).

Now what is interesting is that the light only comes on during light throttle operation or idle situations. When accelerating or at increased rpm it does go away. This to me says vacuum leak more and more. When the car is "acting up" it bucks and knocks and makes weird noises out the intake. (Weird?)

How do I go about finding a vacuum leak? Where do I look?
