1989 suzuki sidekick wont stay running

[Shaarc5]

1. Key on and idle map test good on both.
2. Map hoses are good, map filter not clogged, no a/t port on mine.
3. I redid all my TB gaskets. I made my own gasket, just like yours, since no parts stores had them. Still runs same.
4. I blocked brake booster hose as stated. Runs same

Thanks for the replys. Is it time for me to get a scope or is there more tests I can do?
