okay while setting minimum air....
the tech article says to have it in drive and set it to 450rpms but my TPI shuts off at 600-650! what other "gremlin" is making it die!!!?

I already changed my IAC,O2sensor,EGR valve and adjusted my TPS (was a low 44)
Do you think something's wrong with fuel delivery?
