Misfire Fault Code

[nookatee]

Ok, so for a little while now I've been trying to decide how to attack this problem. My car didn't pass inspection and even after I cahnged the 02 sensor, I'm still running too rich. I've decided to try to pull the fault codes, except that a.) the manual method of pressing the gas petal five times is really difficult and b.) i think some of the neccessary light bulbs are burnt out. I'm still not sure which light bulbs to buy (there are two different ones at Bavauto.com and i don't want to buy 2X as many light bulbs as I need). Any advice on the light bulbs would be valuable.
This post however, is to determine if there's a way to find out if one of my cylinders is misfiring, perhaps by hooking something up to the cylinder. I noticed a little bit of oil in the spark plug well (blown valve cover gasket) over one of the cylinders. I have a feeling this could be causing a misfire because it looks like the oil in the well is seeping onto the spark plug.... :-/
Let me know what y'all think.

Get the codes read at Autozone. Then come back and tell us what's up. The codes will indicate if a misfire has been detected. ALso, if you have them read, you don't have to worry about the bulbs. Replacing components in the instrument panel is a pain in the neck anyways. DOn't go there unless absolutely necessary.

I've heard that Autozone only does OBDII fault code readings. My '93 is an OBDI

If you hyave oil leaking into your spark plug recess due to old valve cover, this will cause missfire, loose power and make your engine run shitti. The oil accumulates on the recess and then it floods the spark plug, and then the plug looses contact.
Raplce the valve cover gasket, not a hard job, then clean all plugs and electrical contacts good.
If spark plugs are old, just replace them .
