Was driving for about an hour and car was driving good. All of a sudden, when I went to turn on to my block to come home, the car just started shaking, power steering went out, and it died on me. Was able to start it back up but had to pump the gas while doing so. Got to my driveway and it died again but was able to start it again and park it. Left it on for a bit and let it idle. It was shaking like crazy, sounded awful, and rpm was all overy the place. Not a happy camper right now, but lucky this happened when I was just about home. It's a 91 tt btw. Any idea what the problem could be? Appreciate any help you guys can give, thanks!

Little update: This morning, I started it up(started right away) and I heard knocking but the shaking was minimal. As soon as I put it in reverse, it started shaking violently. Then I put it in drive and it was still shaking and sounded like it wanted to die. Kind of sounded like a lawn mower. Every few seconds there was a low *boom boom* sound...sorry, can't explain it better. Wanted to try getting it to the mechanic but don't think I'll make it. The shaking also happened to me before, about 2 weeks ago. But it was only when idling and wasn't happening when I started it again.

You have a rather large misfire going on there, and from what you wrote I'd begin with your fuel injectors.
Your first steps would be to clear that area carefully, and remove the connectors one by one which can be a hassle, looking for corrosion and continuity. Most likely a good cleanup of the expected green crap will get you going, but inspect all wiring and connectors in tat area for the same corrosion and clean, clean, clean...IACV, PTU, CAS and CTS sensor connectors all suffer from corrosion so more work is beneficial.
Also, with the way you wrote your post I'd also ohm your injectors following the steps in the online service manual you can find in the "everything you need to know about the Z32" sticky on top of the Z32 page.
The OSM also has all of the other test procedures and some troubleshooting areas to help you diagnose and repair your problem if it's more than I covered above, or be able to point your mechanic to the right area if that is your course.
Good Luck!

Thanks for the response! Actually took it to my mechanic and he saw that there was a leak. Told me I needed coilpack lower boot, so I ordered 6 of them (https://conceptzperformance.com/Cart/de ... hp?II=8070). Hopefully that's the only problem.
