Sounds like something was left disconnected or it needs an idle learn any check engine lite any vacuum leaks?

aircleaner assembly must be installed and have no leaks at all to run right unlike older cars. the dist could be off a tooth. i had issues w my spider injector right after i changed my intake gasket. is it giving a code? let us know what u find out please
