So, got some more issues now. The car will start then die out after a little bit here's the codes:

E12 No distributor signal
E39 TCC/VCC engagement problem
E41 No Cam Reference Signal from Ignition Control Module
E52 PCM Memory Reset

F32 - couldn't find the definition

7.0

When running the engine vibrates a lot and sounds awful.

Could the PCM cause all this?

I'd start with the ICM. I think it is on or in the distributor cap.

Yep, it is a $20 part inside the distributor. Take it to Advance Autoparts, let them test it and buy new one if necessary. Use thermoconductive grease when you install the new one (mine came with grease in a package).
E39 -your transmission does not lock up. Not a big deal, but will affect the fuel economy slightly.

We don't have an Advance here in Winnipeg.....

I think the transmission might be relted somehow because this all showed up at the same time?

I do not think so. Your parts stores probably can test ICM too.

You have two codes that identify a likely problem with the distributor.

I was told on those to always completely rebuild them. If it is electronic and inside the distributor, replace it.
The hall effect switch, the pickup coil, the ICM, and the wiring if possible.
I have only done a couple but I know some guys have gone round and round with those trying to get rid of one code only to end up with the same issue.
If you are handy with tools it really isn't hard to rebuild the distributor but getting the timing set going back together can be a bear.
I'd also recommend using FACTORY parts and DON'T buy an aftermarket reman distributor unless you want more issues later.

The TCC code you CAN ignore and see if it comes back.
The 52 is a memory reset indicator, it means you unhooked the battery or something, that's all.
The F code will be in another module and completely unrelated.

Ok, I'm up at the lake and the only dealer out here is GM, but does not deal with Cadillac (Chevy, Pontiac, Buick). This is a job that any certified GM mechanic would be able to do, right? Could this cause shaking as well?

Any dealer should be able to get the parts. A Chevy guy should be able to rebuild a distributor, although he might be amazed at the extra junk in there.

Define this "shaking"....

Not really sure how to define it, basically the front end shakes/vibrates when the engine is running. To the point that its obvious there is a problem I guess.

It sounds like all this is accompanied by a misfire, should be easy to isolate while working on the dist....

If the distributor is damaged then you can expect to have ignition problems. The spark is controlled by the computer based on data collected from the cam sensor and other stuff, with the assumption that the distributor has base timing set in the correct position. In this case it is apparent that the computer is unable to fully read the ignition data so your timing is probably all over the place, producing the thumps and shakes.

I'd start by checking the wires coming out of the dizzy and if those are good then R&R the internal parts.

I would not drive it.

That's what I thought too. Would it be ok to limp it 15k or is that pushing it?

All right, guess I'l get it towed. Do you know the ballpark price of a rebuild of the distributor?

Make some phone calls to places that may be able to replace the parts mentioned, and ask about a figure to do it.

It's been a while since I did one, so I couldn't even guess really.

I have a feeling it's going to be the maximum amount possible so I wish you luck finding a nice place that won't be too hard on you. :duck: I wonder if GM still offers a new distributor for these cars and how much they cost? It may be cheaper to buy a new GM distributor than to pay somebody to replace all the parts in your old one.
