AFM gone? Stalling/spluttering after releasing revs

[Marky]

Have you tried what I suggested with the gate yet? Hose direct to bottom port, top one open to air, and see if winding out the screw on top does anything

Though chances are its got some ridiculous 20psi spring in it or something haha

[slystiguy]

Oh you mean just run a line from the turbo nipple to the wastegate?

[Marky]

Yep, that will give you just spring pressure whatever it may be

Wont be the cause of your leak and stalling tho

[slystiguy]

Yea still the same hits cut very fast haha. Can you just cut a spring down?

[Kiwi_Fozze]

that\'s gone into the bottom wastegate port aye?

cut spring? i wouldn\'t, if you shorten it, you run the same issues as cutties in suspension, spring rattles around if done wrong.

[slystiguy]

Yup going to the bottom port. I\'m going to take it out tomorrow see what I can find. I\'ve emailed 41 auto to see price and availability but would prefer to find something local if I can (just so it\'s sorted fast)

The other thing to consider will be the condition of the seal It\'s pretty old

I removed the manifold today as I\'m doing the split rails mod. I found one of the vacuum lines for the regulators was split and another which went to what I assume was the charcoal canister thing wasn\'t on at all.

Would this be enough to cause a vacuum leak and the problem I\'ve been having?

[Rosssub]

Definitely. Double Vac Leak, 1 at Canister (CEL 45), one at FPR causing low fuel pressure? Both messing with MAF/ECU/AFR/Idle.

Edit: Have you changed/checked your Waste Gate Spring?

[slystiguy]

I\'ve removed the larger spring and I\'ve got a 11psi spring in it now. Runs mint. Except that idle issue

Yea thought it could have been the cause of the leak. I\'m redoing all the fuel lines and also the breather lines so will be able to set it all up nice and cleanly. Then hopefully the issue will be resolved and I can get my tune and cert

[Marky]

Explains the horrific gas use too

No feed to reg means super rich off boost, and then going lean on it

Neither is ideal neil

[slystiguy]

Well I should have it fixed and ready to test by the end of the week. I\'ll post back the results when I can
