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 .

I wouldnt even have noticed had it not been for the P0076
Thanks for helping me anyway

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%

Try this : run the engine for 30 seconds at idle , turn it off , wait 1 min , then watch the ssv while someone turns the ignition on then off.
The ssv should open as ignition is switched off then close a few seconds later.
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 !
