I recently had my immobilizer control unit replaced and about a week after getting my car back i started having this issue.

Car wont start unless I'm applying about a quarter inch of throttle for a few seconds. Other wise it starts and stalls out.

Thought I had bad gas but 5 tanks later and an injector cleaner still doing it.

Pulled code and this is what I got: (each line displayed, not sure if any lines are together)

P1800
Mil off
Monitrs
0 Inc
7 Ready
Misfire
Fuel Comp
Catalyst
Evap
02 Sensr
02 Htr

Passed Emissions, Runs great once started. 2002 w/192K miles

Is there a particular item someone would tackle first to try fix the reason the car stalls after starting. I was also thinking that my problem may not even be associate with any of these codes.

The only thing you typed in is the P1800 at the top of the list. Everything after that is unintelligible gobbledegook. If there are more codes than the P1800, please list them.

P1800 is the VIAS control solenoid valve. It is mounted on the intake manifold on the right side towards the front corner of the manifold. Get that fixed and there is a good chance the starting problem will disappear.

see page 24 for a locator diagram.
See page 686 for more info on P1800.

At first with this problem I was only getting the P1800 code with "No" engine light on. Yesterday the engine light can on for its first time with an additional code P0506 "Low Engine RPM". After further research I replaced the vacuum hoses to the VIAS and cleaned the throttle body...

Problem Solved!!!!

Codes reset, fingers crossed they don't come back.

Good to hear.

Everything you typed below P1800 is just the usual stuff an OBDII reader tells you about your car. Those aren't codes, only P1800 is.
