OK, after my car is warmed up to operating temp, when im at idle, it dips really low sometimes (like 600 rpm) then goes back up and down. It feels like its going to stall. So far i have a EGR block off plate, and i got a new map sensor. It still does it!!!! i have a cel for teh block off plate and ill recheck the code, but i believe its still code 12 (egr) so that souldn't be a problem.

Also, whenver i accelerat between 2k and 3k rpm, the whole car like vibrates/shakes and it is not smooth

Could htis be a clogged catlytic converter? Fuel filter?

you shouldn't have a CEL if all you have is a block off plate, if you removed the egr completely then thats a problem right there. you need to leave the egr valve in place other wise the car freaks. start by putting your egr bolted over the block of plate , with everything plugged in normal.

possibly take you IACV off an get some carb cleaner and clean that out. but start by getting rid of the CEL and then reseting the ecu
