I own a 1988 oldsmobile cutlass cruiser station wagon. It has a 2.8L 6 cylinder, 4 speed, front wheel drive automatic. The car runs phenominal but over the past few months ive realized a few problems begining to sprout up. My first issue that I have is that if it should rain or if it is a damp day the car will start but will begin to miss fire badly. After a while the missfiring quiets out and returns to normal. My second question ive been told may concern the vacuum to the car. The problem is that ive been noticing transmission fluid showing up inside of my air filter. Ive noticed that the vent for my crank case has been sucking in air rather than blowing it out could these be related?

First, at night in the dark, start the car and mist it with water. Watch for sparks or arcs from the plug wires and around the distributor cap. I'm confident that is the problem. If you see them, replace the wires and distributor car. Also, pay attention to the coil wire too.

As far as the ATF in the air box, that is interesting. Check the transmission for a vacuum modulator mounted on the side of it. There will be a vacuum hose going to it. Remove the hose to see if there is ATF in the vacuum hose. If there is, replace the modulator.

Let me know what you find.

Well at this point now ive already replaced the vacuum modulator an this has remedied the fluid showing up into the filter canister. As for the stalling problem it may have been also caused from the original vacuum because of the amount of fluids kicked around because of it. I will try to spray the engine and wires but keep in mind this car has no distributor.

Well, one problem down, one to go. As far as the wires, try that and let me know what you find. If the problem happens more in damp weather, chances are that is where the problem is.
