The cause of p0102, P0103, and P1506 besides MAF

What is your question?

My 2001 Mazda B2500 has a p0102 and a P103 code what other things could cause this code like maybe fuel pressure, vacuum, fuel injectectors ? What do I check and what should I look for? It also has a P1506 code. These are after a P0101 code and a IAT intake temp sensor code that went away after replacement the IAT sensor & gromit .and erasing It. Has a low Idle and dies at stops sometimes or often. Thanks

What makes this problem better or worse?

P0102, P0103, & P1506 codes sometimes dies when at idle or come to a stop
