You're running lean. Clean MAF, check fuel trims and O2 sensor). It could be a few things causing it (O2, fuel pump, MAF, leak, etc). Have you done a smoke test?

 

i never done smoke test .(i do not have smoke machine) the car hard to start when it sit over night but when engine run it smooth no shanking. When engine warm up it run and start up fine .at this point i did not think fuel pump or vacuum leak, the most i think something go wrong with my MAF sensor .Thank a lot for help .
