Looked at another members car today to try to sort a few things out for him.

 

Basically it's running OK now apart from 2 things:

 

1) It cuts off when dropping to idle from high(ish) revs. Suspect a boost leak or problem with AAC etc. Anyone had similar problem and fixed it? No obvious vac leaks but I think that's the most obvious one. Pulling off the AAC connector has little/no effect on idle so that could be a possibility. Does it when stationary too, so not PCV's

 

2) Won't boost past 16psi on SE stage II hybrids, even tried setting the duty cycle to 100% for a burst! Again, looks like a boost leak to me, but can't hear anything

 

Just wondering if anyone has ahy thoughts to help him out.

 

I've suggested get one of those pressurising boost leak detectors and get it on a consult to chack out the AAC operation.

Cheers

Is the TPS OK? That what causes the stalling from higher revs

It's reading ~0.4v at idle, but it's difficult to tell if it's linear with a digital meter.

Could it be the throttle bodys need a good clean?

It's probably easier for you to look than me!!

Saying that, I doubt it, I'd think they'd have been cleaned before being put back on. Can't imagine it causing that much hassle anyway.
