1985 Gsl-se 13b, crank but cuts off.
 

Need some help.
I got an issue with the car staying running. It will crank, goes to 2500rpm and shuts down. I can keep it running at hi rev if i force it.

Here are the things i done already. New fuel pump, fuel filter, injectors, is keeping a 45 to 50 psi on the rail.

Any help will be greatly appreciated.

I would start by making sure you don't have an air leak between the throttle body and the AFM

Thanks, done that already. Just finished cleanin the tank and lines. Is doin better. Still wont stay idle. Next will be full intake manifold clean up
