I have a stock 305 TBI and when I bought the car the guy had replaced the controle module a while back. He said it needed replaced again because it went bad. The car would run good for about 15 minutes and then die and wouldn't start until it cooled down. After I replaced the module it fixed this problem. My question is, what could be causing these modules to go bad so quickly?

Pleae let us know what module you are talking about.

The one in the distributor, the one under the passenger dash ecm or some other one?

More info to us = better chance of solving your problem.

Any GM part number on the module in question would also be helpful.

the one on the distributor, sorry about that.

The only thing I know about that module is when it is being replaced it is important to use the gel (or whatever that goo is that is typically included with the module) when re-installing it.

The stuff must be smeared on the bottom of the module prior to installation on the distributor. This layer of material helps conduct and dissipate the heat that builds up in the module out to the aluminum distributor plate it is mounted on.

Without the stuff, the module will fry- just a matter of time and cause you all kinds of trouble. Sporadic electrical problems are even less fun than a crabby girlfriend (if that is possible).

I believe this person had a similar problem

Aside from that- parts stores are known to sell the occasional POS electrical part.

Also, they are most likely the cheap modules which is why they are going bad so quick. Be sure to get a genuine AC Delco Module when you replace it. It will last much longer.

The "goo" is Dielectric Grease - and a small tube of it should come with the module.
