What the sh*t..

Take pics of the plugs, and a possible video. Is the check engine light on?

The check engine light is not an effective diagnostic tool... there are very few codes which will trip it and even fewer which will cause it too remain on. ALWAYS check for codes.

Theres still a code 52, like there has been for over a year now. I fixed it a while back. The knock sensor under the manifold was disconnected. And it didn't help anything.
It looked as if the fuel filter had never been changed.. if it weren't for the AC Delco emblem I would think it never had been.

The only leak I could think of would be on the accordian hose to the inlet of the turbo, there is a small crack and it doesn't even come off of the inlet to take in any air.

I'll patch it up to see what it could be doing. This has been going on for a long time, and its pissing me off. I'm about to just give up and do a complete swap.. >.<

So if you fixed it, why is the code still present? Did you remove the efi fuse to reset the computer? Or did the code just not ever go away after resetting? If the last one applies, it sounds like the disconnected sensor wasn't the only problem. Might be time to do the KS rewire

Well, I forgot to say the code went away.. but after a while it came back..
It still does it when the code is off, but once I get going the code pops back up and it runs a little worse. Not much though.

My 87 7mgte is doing the samething, and i'm in the process of replacing the knock sensor now. If this does not fix the code 52 its on to the rewire for the ks. But its one thing after another when you buy old cars. By the way, did you ever sell yours? Cuz I thought of that many times, but cannot go thru with it.
