Question about 1994 Oldsmobile 88
When I start out driving, I accelerate lightly and it doesn't seem too bad, but when I 'm coasting (at any speed) and I give the car light acceleration it seems to have an intermittent miss. This also happens at highway speeds and is very annoying not to mention poor gas mileage.
P.S.....I 've checked the plug wires, coils and plugs. I also looked for bad , broken , or loose connections.

You probably have a bad coilpack - but lets not guess...
Take a voltmeter and check the resistance of the secondary terminals on the coilpack. These are the terminals under the plug wires on the coil. only remove two wires on the same coil at one time. check the resistabce on the terminals and it should be no higher than 15000 ohms. if you see any black powder or staining on the coil terminal when you remove the wire from it then you have to replace the coil AND the wires. don't waste your time replacing one without the other if you see the black under there.
Here is another test for bad wires. take a windex bottle of WATER and a tablespoon of table salt in it. start the engine and spray the plug wires from the coil to every plug you can get it on. turn off the lights arround the car so it's dark. look carefully and check to see of you see any arcing. this looks like mini-lightning bolts. look closely. Good luck...Scott
