Urgent Help Needed

[ECR 033]

Ok,

so i worked out the car was running lean at idle, so i bumped the afm's voltage signal? upto 140% and the missfire is gone completely.

but it still wants to drop back to 200rpm when i let my foot off the gas (also backfires alot) and slowly comes back up to 1100rpm idling perfect.

would this be an air idle control issue of some sort???

i thought about the afm's being to close to the turbo and the plum back bov's messing with the afm's but...whaching the afm voltages there is no sudden jumps or drops etc. when this occurs.

any other ideas?

thanks heaps guys.

ok,

i found greddy air/fuel controller hooked up under my dash hidden away... along with a very hacked-up looking engine/ecu loom.... so i've taken the whole wiring loom from the ecu forward out and replaced it.

it fixed my power fc engine warning light, but it still runs lean at idle and stalls.

the fuel pump warning light is still on the power fc, maybe it has something to do with my issues, i have a new fuel pump... what else causes this light to come on? cheers.

check your fuel pressure

and make sure your BOV is working 100%
