Well my car car is still not running right, but I have removed and replaced the CAS, AFM, ECU , spark plugs , wires, fuel pump, fuel filter and installed a FPR just to see what kind of p.s.i I'm getting (40) or so. It will almost start with everything intact. however, If you remove the AFM from the snorkel but leave the elec connecter on it it will run if you give it just a little throttle before dying. almost seems like not enough gas. Can someone please help me?

Someone correct me if I'm wrong, but that sounds like it's getting too much fuel, not a lack of fuel. A common problem is leaky injectors.

Compression check?
