I agree with Gary's assessment about the Manifold gaskets. The Olds 3800 is a "workhorse" engine as is the 3.3, only you don't see much of the 3.3's on the shelf or in the shop. As this is an older piece of iron it stands to reason that the gaskets may need replacing. If you have a tuned ear you can hear a leak or at least hear the approximate location of ...

The culprit is probably a sticky or malfunctioning Idle Air Control (IAC) valve. Lucky for you it is located right on top and connected to the throttle body. You can try taking it off and cleaning it, making sure not to play with the pintle (plunger) itself, as the gears inside which actuate it can easily be broken/stripped. Use some carburetor cleaner both ...

To check this, disconnect the wire and turn on the ...

Loosen the screws and try pushing down while trying to slide the point set. There is a hole that the point pivot must fit into or it will not seat properly ...

I'm thinking the problem may be your fuel pump. I've seen pumps behave the way you describe with it working on-again/off-again until it finally fails permanently. Plus, your descriptions of sustained higher RPM running with it going up and down could likely be pressure fluctuations coming from the pump. Luckily this is an easy thing to check if you have a ...

If this is a rebuilt alternator from a nationwide parts store, it is not uncommon for these to fail. Take it back to where you bought it and get a replacement. I hate to say it, but it's one of those things. You can purchase a new one from GM and it has the possibility it will fail in two days. Some things just cannot be tested well enough coming from the ...
