Motor dies after first start

[Al]

When I start the car (1990 80) for the first time, it runs for about 5 
seconds and Stops.
When I try again, it takes 5-10 seconds before it fires, then increases 
RPMs  slowly with rough running. To me it seems like it has too much gas.
  After the engine warms  up, no problems. I've pulled the codes and 
they are 4-4-4-4.
Any thoughts?

I put on new filter a couple of weeks ago, but this problem has been 
bugging me for a long time.

Question? I live in a tropical environment, temps are never below 65, so 
do I really need a cold start injector? Can I disconnect it?

My past problem with my instrument panel lights has been fixed.  I 
cleaned all screw terminals and lugs for ground wires. I found what was 
causing my license plate lights from not lighting, broken wires in 
trunk. I fixed them with solder and shrink sleeving.

Happy Holidays to all.
