Ok i have a lsvtec, pr3 obd0 ecu, pr3 head. Im pretty sure its stock fuel rail, injectors, pump, filter. And i need to know what the fuel pressure should be in the b16a engine. The reason is is that i have a problem. When driving my car it feels like it running out of gas but runs richer than ****. the fuel pressure was checked and with out vacume its at 30 and with vacume its about 40. And i guess while driving it drops about 10. Its really weird. Me and the shop dont know what is going on. The pump and filter seem to be ok. Its getting fuel but it just sounds like its either choking for air or running out of gas. Also my o2 sensors arent plugged in because i got a dc sports header and it didnt have the bungs for the o2 sensors. So i decided to just leave them out. But now since this problem i feel that i need to put them back in. Do they need to be in stock position? or can they be put any where? And i have two cuz its obd0. Any suggestions would be great. Thanks
