Default can't keep car running.

Ok I.have a 91 subaru loyole. 1.8 l. Just did head gaskets. On it. Replaced spark plugs cap rotors, intake, exhaust gaskets. Planned on doing water pump timing belt and all pullys this weekend. parts were just on order when job was being done. Car stated and ran fime when job was completed. Need to do idle adjustment and wanted to reset base timing the next day. drove it to test drive and noticed in reverse and drive at idle car wanted to die. Give it gas fine. On park or natural ran fine. Next day cant keep it running. starts and then dies a second later. Checked my timing belt to insure timing didnt jump. (checked 4 times with alldata and second tech and subaru service Manuel.) timing dead on. Performed compression check on all cylinders and all at 150psi or just slightly higher. Withen factory specs of each cylinder. Did a cylinder leak test. All good holds pressure at 100 psi. have spark. Rechecked my plug wires and pkug gaps. All good. Made sure my plugs are in right order. Rechecked all connectors grounds and vacuum lines. All good. Cleaned idle adjusment screw and intake. Made sure battery is fully charged. called it a day. Next day will start and run if above 1000 rpms, if it falls below dies. Performed fuel test after fuel filter. Readings were at 19-20psi starting but running. 23-24psi at running around 1800-2000. Max pressure with vacuum line disconnected at regulator and return line pinched off is 39-40psi (this seems alittle low) plan on doing fuel test again before fuel filter to see if pressure rises at all tomorrow. Wanting to see if anyone had any ideas or suggestions. I dont have an obd1 scan tool to check codes. Just a snap on for obd2. Im about to start looking into electrical like a computer or something but before o get to that. Wanted to see if anyone had any ideas or knows somethin I dont on these older engines. Any advice would be awsome.

I had a similar problem on a Ford Expedition that I had just replaced the intake manifold gaskets on. Turned out that the IAC had gotten clogged with carbon, so I used the "IAC service tool" on it and it ran like a champ. The IAC service tool is what we call a small metal hammer.
