Are you using a factory airflow meter or a Z32 or G50 unit?

 

[Sphinx415]

z32, new IACV, new plugs, changed tps twice, i honestly have no idea what brake booster hose your talking about....but i checked all my vacuum lines and they are all new....brand new cuz i changed all of them recently.

im at a lost with this problem....im going to try a new air flow meter....but if that doesnt work....im lost...
