So I had my solenoid off to have a nose at it. filter screen totally clogged though some brake clean shifted it, also sprayed some cleaner down the vac pipe outlets with some "stuff" coming out of the other outlet after a few sprays, sprayed some penetrant spray back down after that to lubricate things.
Give it a test drive later / tomorrow and see if any improvement to things, if so then its a new solenoid on the purchase list (then again it is OEM, one of the early ones with a metal ring between the 2 halves of the body rather than being glued together as the later ones were) albeit one of the fasteners was seized solid and the rubber ripped so its now held by 1 for the moment, not the greatest of designs tbh...

After I "cleaned" my solenoid it ran well for a few minutes then got very laggy then came back, so ordered a new solenoid from GPS as that seems to confirm my suspicisions given that was the only thing I meddled with. Its OEM and very early in design so I reckon its due a replacement, £53 and change from GPS for a genuine replacement.
On a sidenote this car is suffering a spate of stuff wearing out in one go.....

be interested to see if this cures your issue. Parts do wear out and I think a lot of people just assume its going to be the usual bits that go but in reality all parts wear at some point

A new boost solenoid has been found to be required on most of the z19's that I have remapped recently. They are always knackered by 10 years/100k.

That's interesting to hear. Mines on 152k and have had my suspicions that it might not be working 100%

Quite catastrophically yes, but I didn’t dither in getting it fixed along with new consumables like it’s 3rd cambelt dmf and clutch kit amongst others

Just swapped mine, big difference in performance /mpg however still getting a squeal on hard throttle application. Does that sound like the turbo has got excessive play? @Teapot any recommendations for a hybrid turbo supplier? Any on eBay any good? -gap , BTP etc?
