UPDATE: I did the coil test on it, and noticed that when I removed the ignition wire to cylinder 3, the car would struggle to stay on. When we did the test again, it shut off completely. Any ideas of what that could be? A buddy of mine that lives in Reno told me, after explaining what it was doing, that it could either the distributor or the ECU. What do you guys think it could be??

 

It sounds like cylinder 3 is firing properly; what happens with you pull the plug wire (one at a time) to the other cylinders?

 

Only cylinder 3 was misfiring, because all of the other cylinders were working fine. Once I tested cylinder 3, the car was struggling to stay on. I did the test on the same one after I had checked the other ones, and it shut off completely. When everything was back in place, I went to go start it, and it didn't start right up.

 

That doesn't make any sense; if you pull the #3 wire and the engine struggles without that cylinder firing, then the issue is with a different cylinder.

 

Are you sure it isn't that cylinder only?

 

If the engine slows down causing it to chug when you pull the spark plug wire, then that cylinder is firing.

I asked this earlier; what happens when you pull the wire of the other cylinders?

 

A small change happens to the motor when one of the spark plug wires are removed. When I put it back on, it goes back to normal.

 

So pulling 1, 2, and 4 causes less of a slowdown compared to 3? Sounds to me like you've got three bad cylinders and one good one.

 

So what do I do there? Is the cylinder head bad or do I change the gasoline?

 

Gasoline will not solve your issue. The first thing I'd do is a compression test; preferably a cylinder leak-down style of test.
