7M - Most common area for a Vacuum leak?

[JustCallMeOrlando]

Remove it and fill it full of water is the straight forward solution numb nuts here would probably do.

sounds like the knock sensor wire is almost there.....doesnt need much to get it wired up by the sounds of it.
Damo i'l wire that up for you.
Once that is eliminated we can check for other codes aswell, then start looking for boost leaks, more often than not there will be a dirt mark where the leak is, especially if it on the cooler or any other aluminium bits.
The idle could still be a faulty ISCV even if its been cleaned out. Those vac lines on the PS pump werent very tight either, although that would cause a high idle not low. Vacuum leaks will cause high idle not low idle. if the idle is consitantly low it could be ignition timing aswell. Which could also cause low power and over fuelling. The very early boost cut kind of points to boost leak though, and would also account for the over fuelling and power loss.

i had a spectacular leak that made my car idle like it had an 8 in it, but off idle, it ran like a dream.

get a bit of silicon, and a PVC end cap for storm water drains, hose clamp the silicon to the intake of the turbo, and the other end onto the pvc end cap, whack a pressure fitting in the end cap, and using a compressor, pump some air into it.

you'll hear it hissing where it has a leak.

nearly every single turbo car ive ever seen has some sort of boost leak.

damn turbo shit.

seemed that a leaky factory BOV was a major source of boost leakage..
luckily I had a new GFB Mach1 layin around.. so that sorted that out..
still hits boost cut at 8.5 - 9psi.. dunno what thats about?.. maybe cos I'm running an auto ECU?..

also - no more check engine light! WooT!..
good to have another knock sensor wired up.

The car is alot smoother and accelerates without hesitation now!

just need to get more boost into it to get more power!

anyway - a re-run at the drags will be happening in the near future to see what the car is currently capable of.
I'm thinking a mid/low 14s
