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.

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.
