ok so i just swapped out my d16z6 for a d15b vtec.. i currently have I/H/E and skunk2 intake manifold...so this morning i go to warm it up before i head out to school and it turned on and it died on me before i got out the car..i turned it on and gave it some gas and it was at 2k idling cold..so i go inside my house to get my stuff and i come outside and its turned off.. when i put my intake manifold on i didnt put the IAT sensor on..you guys think that can be the problem?? it wouldnt wanna stay on cause it was cold ??? the hood was open all night alsoo..

 

well i looked under the fuse box and i had the "back up" fuse blown..i replaced it and it starts and like 2 seconds later it shuts off..

 

The iat temp helps the ecu decide how much fuel its going to send to the car while its cold. It basically determines how dense the air is and adds fuel accordingly. WIth out it hooked up the ecu is blindly adding fuel using the map sensor

 

i pulled out my spark plugs and they had unburned fuel on them too

 

anyone else? plzz!
