My on board monitoring codes R026 TO37 says these are active 95 DeVille 4.9

What is your question?

I'm driving my car it'll be driving fine then all of a sudden it'll start stalling I'll push the gas nothing happens but the car is still on I'll let off the gas next time I push it it'll start backfiring acting like it's getting no gas it's choking itself out after 3 or 4 minutes I can push the gas and it'll straighten itself out and take off then it might be a week to 2 weeks before it does it again and every morning when I started it's rough to start I have to rev the engine up for about 3 minutes before it all no check engine light

What makes this problem better or worse?

After driving for 2 or more hrs

How long has your 1995 Cadillac DeVille had this problem?
