Forgot to mention I have a P0076 and now that I think of it the issues happen at 7000+rpm
Can a broken VDI cause the engine to run lean too?

No ...VDI wot cause it to run lean . Suggest you get hold of a logger so you can see what your AFRs are. That will enable you to hone in on the issue.

I mean anything that can cause detonation/that sound
I have torque pro, lemme set up a log

No , I can't see how VDI can cause that sound ...... unless it's really flogged out or something like that.
See if you can get AFR , RPM and load in the log

Turns out it was the VDI after all...
I took the car to a shop to drop the transmission a couple days ago so I could fix my throwout bearing and I left them alone for 5 minutes. When I took out the intake manifold to replace the solenoids today I noticed the VDI vacuum line wasn't even attached to the solenoid. I replaced the dead solenoids and plugged the vacuum lines back but it looks like I lost my engine. Rough idle, accelerating feels like the engine is filled with molasses and it takes ages to start even when it's cold. It wont start when its hot
I have no flatlines and no sounds now but its too late

Well ...it wasn't the vdi ...it was the vacuum leak from not having the hose connected ..... I can see how that would drain the vac tank at the rpm the vdi turns on and then cause the SSV to close .....which would then cause a lean condition.
Really sorry we didn't work this out before you killed your engine . A lesson for both of us really .

The P0076 is a code for an electrical malfunction of the VDI solenoid and nothing to do with the hose being off which is why I didn't suspect it was causing the noise. A perfect storm for killing an engine really .
So when do you think the engine died ? Don't understand how leaving it with the mechanic had anything to do with it ?

I'm not saying the P0076 was any indication of the line being off, I mean if it werent for the solenoid conveniently dying at the same time (hence the code) I wouldn't have taken the manifold off and noticed the line just hanging around. No hissing sound now, looks like that was the vacuum leak. LTFTs at 1.94%

This tests the solenoid,the actuator and also the vacuum tank for leaks.

If solenoid and actuator work while engine is running but not during the above test ...it's a vacuum leak.

Also : again after 1 min, reach under the intake manifold and pull off the hose that goes to the vacuum tank ... you should hear a sucking noise as hose is removed. No noise ...no good !

Just tried this, mine doesn't seem to move at all, can't get my bloody hand down to move it by hand though
