No codes no engine light. What i've done was cleaned the o2 sensors MAF, changed the pcv, changed the coils and spark plugs it has a new throttle body new alternator new battery, checked and cleaned the injectors changed the coolant temp sensors checked fuel pressure checked vacuum leaks did a compression test changed the transmission fluid and filter also checked for head gasket leaks checked the fuel pump timing chain was replaced and parts with it i think thats it. thanks for the reply.

happy to provide intelligent reply after you OBDII scan your vehicle, post Codes here. Lots of things can cause rough idle on warm engine, e.g., misfiring. You've got that fantastic diagnostic tool available, so scan it now & avoid guessing.
