b16a swap not holding idle *Vid link included*

[qikteg]

Hi guys,

so my b16a swap is turning over, but is idling rough, for a few seconds, then dies. if i open up the throttle, it'll die quicker. fuel pressure is within specs

there was an intermittent EACV code being thrown, but thats been fixed and isn't an issue. there's a Vtec pressure code being thrown too, but i'm assuming that won't affect the idle.

any ideas?

thanks

*EDIT* Issue resolved, the map sensor was wired incorrectly. Its been fixed, and its idling now...

sounds like you got noo air going into your engine

[qikteg]

but when i open up the throttle, it dies even quicker. and if the throttle is open on crank, it'll barely get going

maybe ur dizzy? or fuel pump?

[ninzee]

mayb your filters clogged happen to my m8s ej8 once cause i dodgy mechanice "accidently" left duc tape in his cold air, dont ask me wat he was doing with duc tape in the 1st place lol

[turtle187]

my assumption is ur fuel pump or u can check ur FITV

[qikteg]

fuel pump is a brand new walbro, fuel pressure remains within specs during the short period of idle (at ign its at 35psi, during the idle, jumps up to above 41psi).

no airfilter, running straight off the throttle atm.

FITV?

could be the dizzy, but i've done a full spark test, and all plugs are getting constant spark whilst cranking.

leads on the right position on the dizzy cap ?

o2 sensor??

[qikteg]

leads are in the right order

o2 sensors were 2nd hand, but the ECU isn't throwing up any codes about them

Stu....lumpy Cams?



Clean fuel I would assume

[qikteg]

Im running a jdm PR3 ecu to a b16a2, with a retro fitted harness... What octane fuel do jdm ecu's require? Could this be an issue, or would it just run crap...?

Lol, headers only, no cams yet
