alright... i got the b16a SiR II motor and when i bought the car the motor was in there... well now the car isn't running well at all, it is running rough and now when i start it it runs some then dies... and i have to give it some gas for it to start.

i pulled the codes off my ecu and i got the codes for map sensor, vtec solenoid, and o2 sensor.

Well i've been looking my damn a$$ off for the damn map sensor and cant find it anywere. on the jdm b16a's the map sensor isn't on the TB so it is suppose to be on the fire wall with a vaccum hose coming from the TB to the map sensor. Well i followed every vaccum hose and the whole harness in the engine bay and i cant find it, neither can my dad. my dad says i dont have one on there, thats prob why its throwing a code on that part. the car ran fine before but there was always a engine light (i never did check it then)before it always idled up and down bout 2 times then cleared up fine. but it just now started running rough.

so i dont have a map sensor and idk why or we just cant find it for nothing. so i got a o2 sensor on the way. so when i install that and clean the screen in the vtec solenoid maybe that will fix the problem, but idk. What do you all think?
