sparks are new, coils are new, fuel pump and relays are new, i think that something is sticking to my throttle body...that sounds close...also people told me to flush my ecu by putting the old chip back then booting up, then seeing if all is ok, if so, then i should put the new back and see how it goes...i think more and more its not my ecu but internal parts, cuz after the car shuts off, i leave it alone for like 5 min, and its fine...its a random problem...but very severe..
