Yep, that's the Ignition Module. Has 4 connectors around the periphery.

Where does one come by this stuff? It'll cook the IM without it huh? Thanks God for the forum.

It's "unobtainium" that can be found at Radio Shack. Just ask for heat sink compound.

LOL, thanks Dominic.

What Dominic said.

With CPU heatsinks, only thing to NOT do is apply it in a 'ring', 'cause you can get air trapped, and air holds heat. Think insulation.

I tried to put it only in the center, and press, to work it to the edges, but that took forever. Lifting it to check is not easy. And that's what made me put more down - too much perhaps. Probably why it says 'in 4 spots'. I don't know either what kind is best - Silver-based, Copper, Silicone...

If GM didn't have problems with the record-setting cars, there MIGHT be a little room for error. And maybe not....................................

I just went to autozone an purchased it in a small box with 2 small packets inside the box.

It took about 1.25 packets to coat the entire surface with a putty knife.

A word of caution on the heat sink goop application:

It needs to coat 100%, as mentioned, but very thin - so thin that you can just see the aluminum through the grease.

AND! Be double damn sure you don't have anything like a grain of sand between the DIS module and the plenum; it is a killer, and the module is near unobtainable! In fact, unless there is some reason you must remove it...don't.

Just sayin...

To D side, to clean up a little before pulling the plugs (anybody NOT like A/C Delco 41-800 / 19250872) ?

Is there a better over-the-counter plug? I ran Split-Fires in all my fleet vehicles; don't know that they were any better...

Make some room:



What is this sensor under ECM (besides DIRTY)?

[mike100]

That's the map sensor to detect the presence of vacuum that operates the secondary throttle plates. It sets a light if the vacuum isn't present due to a leak etc.

run the $2 ac-delco plugs that came with the car. They are so easy to change on this engine don't bother with double platinum or exotic heat ranges on a stock engine.

Thanks there Sir...

It would light a 61 code then???


The emblem was loose. What adhesive to stick it???



Cleanup is gettin' outta' hand. Those pimp-mobiles with $2k rims on the corners look great [not], when they're sittin' on the roadside broken. And I have 'hesitation' to keep in mind...

So it will be easier next week, being clean at least, when I have to do breakdown again to solve this gig.
