wires, plugs, coil packs, new alternator. But now i
start it up its still running like crap at idle, revs
good, but stalls when i open the car door, or put my
foot on the brake, or try to put it in gear just shuts
right down with a check engine light and not
flashing any codes.

how is the fuel pressure? change the fuel filter and see if u get better idle. also rough idle can be from a miss fire. did u change the module under the coil packs?
