i have a AWD 98" chev astro van V6 its recently had issues going through DEQ so almost 2k later heres what we fixed so far so you can emilinate it has a resolution. the mainfold gasket was installed incorrectly now replaced . cylinder number 3 injector replaced. pvc valve replaced cat converter and all three o2 sensors all replaced. full tuneup . oil change . now heres the issues . i have two codes which come up but until i get to the machanic monday i wont know if either both or one of two codes are coming back up one was both banks running lean and the cat converter im assuming that since the o2's and cat were just changed its not that . but the problem i have now is that on start up and only onn start up it will idle oddly and once i enguage the gear from park to reverse or drive and press the gas peddle it chuggs out losses all power and i have to bacck almost completely off the acccelorator to regain momentum again. this occcurs weather hot or cold and only after its just been started and just taking off . once im moving this doesnt happen any longer even if at a stop or not. any ideas ??? also the fuel pump its self was just cchecked and it didnt have its full pressure but wasnt terrible either . the fuel filter was also changed recently . HELP please
also i forgot there are two vacume hoses on this van and both are cconnected and just fine .
