[Hanaldo]

Stock bov?

[top13s]

yeah i have a stock bov and i think its leaking,. i wanna get the de intake pipe so theres no bov mount., i love the sound of a turbo dose

wats the best way to clean the afm and tb?? carbie cleaner ??

[wolverine]

electrical contact cleaner.

[top13s]

also every now and then when it does stall the battery light flashes as its stalls in mine, but it dosnt in my mates mums

[Hanaldo]

If it's leaking, that could be the cause. Means air that the AFM has registered is never reaching the engine and hence you run rich and stall. But that's making a few assumptions.

When is it stalling, on decel or idle or?

[top13s]

somtimes at idol but mostly on deceleraton. more so as you come off boost, but some times it happens as your slowing down

Reset ecu, clean AFM, clean AAC

Do these simple things first

I hate AAC valves

[Rolls]

Is it after revving it out on load/boost then clutching in straight away? or does it just randomly stall for no reason? Does it also hunt?

If it is the last two it is most likely the AAC valve, take it off, soak in petrol cleaning it out then pressure clean it as well.

First one is most likely tune related with it running rich on deaccel, can often fix this up by tweaking the map.

I lold.

[Rolls]

lol, just block the bov off with a coke can gasket, that way when you get sick of it a month later you can stop the dosing.

[top13s]

yeah it seems to more often stall after boosting, what do you mean by hunting??

coke can gasket hey i like the sound of that idea. i jus need a front mount. i have one lined up jus need to get the cash
