98 VT Berlina Commodore, running rough, idling rough

[Crazykitten]

So ive tried so much to fix this issue, done plugs, leads, coil, even replaced starter motor (as it wasnt disengaging...) and it is still running rough, hot or cold, revs just jump and fall and i am at a complete loss as to why. it stalls though when it is cold (its an auto)

i could use ANY suggestions right now >.>

Mine is running rough too the mechanic told me I need to check that the injectors are clean, maybe same problem here?

Thats a possibility, i was going to check the air intake next but i might do injectors first
