Car starts but won't idle.

I have a 89' caprice with a 305 in it. It sat for about 9 months and I am trying to get it going again. I tried starting it and it starts up but won't stay idling. I can give the throttle a little push and it will keep running. I have replace the TPS sensor, fuel pump and fuel filter. I don't know where else to look.

Do you
have the same problem?

Look for vacuum leaks around the throttle body

the iac motor may be bad or carboned up

the injectors may also be dirty as well.
