You replaced spark plugs? What brand and part number?
AC Delco 41-103 iridium I hope!

Have you inspected the connector wiring at the throttle body?

well i can’t even relearn the throttle body because i can’t even keep it running long enough. it dies immediately. but i pulled the plugs yesterday to check and make sure i had good spark and the brand new plugs i put in were completely black. if that helps anyone lead me in the right direction.

Oldblue

Which plugs are in there?

Black plugs makes me think the butterfly is stuck closed.

Oldblue

Yes, running very rich.

do you think that maybe the throttle body i got is fualty ? i did get it out of a junkyard. but even beofre i replaced the symptoms were the exact same and didn’t even change once i put the other throttle body on.

You need to put a scan tool on it and see what it's doing.
Need to see what the load devises are doing. MAF is first. See what the PCM is commanding the injectors. Could be they are being commanded for idle which would mean your injectors are bad.

Switch back to the other throttle body, see if there’s any changes. And please , answer me about the spark plugs!
