the last thing i did was i put my stock intake manifold back on.. after i did that i noticed that if i was to stop all of a sudden my car idle would drop close to zero.. or even if i was to down shift from 3rd to 2nd it would sound like it would die out.. but i just thought it was because i just put my stock intake manifold back on but after 2 weeks later this problem came up...

Did you disconnect the battery afterwards or during this process? Different flow with a learned older flow with screw up your o2 sensor output on the computer.
That ECU will "learn" your driving techniques and will be thrown off when hardware is changed.
Try to disconnect the battery and run it for about 50 miles or just drive it down H1 (not during traffic hours though, lol) and put on the cruise control. Turn back around and go home. Shut her off and get back with us tomorrow.![Big Grin](https://mitsubishiforum.com/forum/images/smilies/biggrin.gif)
It should run somewhat rough after first reconnecting the battery but then it should smooth out. Don't idle it in the driveway longer than 5 minutes or it will start to learn that 5 minutes of idle.
One thing to do while the battery is disconnected is to press and hold the brake pedal down to remove any residual power.

couple daysbefore this problem happened i changed my positive battery terminal so i did take the positive cable off and changed it..my car was running fine then.. and now this problem happened.. so dont think it has anything to do with my ecu or battery cable.. changing o2 sensors and crank angle sensors tomorrow.. let you guys know an update on how it runs after

Ah ok.
I would change out the crank first, drive it around the block after the motor has warmed up. That way the parts can be deduced (thanks for that word KN). Why are you changing out the o2? Just old or is it giving you issues with gas milage?
