I recently baught a 1992 subaru loyale for $200 and have been filling it full of parts and I replace the entire throttle body bc it was cheaper then replacing the fuel pressure regulator and it ran great for 1 night then the next day it starts idles for a few secconds then dies and I notices when it did run fine it idled at about 1k rpm is that normal any help would be amazing

T in a fuel pressure gauge, at the throttle body.  It should be 21psi.

Could be a stuck IAC or bad TPS.

 

It quit running completely and fuel pressure is good it only runs of starting fluid and it will idle with starting fluid but as soon as you stop spraying it dies
