I'm new to this forum. I have a 2000 Tiburon 4 cylinder. The engine light came on last night and hasn't gone off. I checked with Auto Zone and error code was cylinder 1 misfire detected. The engine sounds rough now. I would appreciate any suggestions. I also have been having a problem with the passenger side power window. It stopped working several months ago and I'm having problem putting gas in the tank. Outside of these problems everything else is okay I guess.

I had the same problem on my 1999 tiburon. I ended up putting in new aftermarket wires and auto lite plugs, and the problem still persisted. The manufacture recommended plugs are iridium plugs. You have to use the iridium plugs. The spark is hotter and you get a much better burn. Once I swapped the auto lite ones for the iridium ones, my problem was gone. Hope this helps.

:00000732: Matt. I'm going to go along with the rest of the advice you have here and say replace the ignition wires and plugs. Go for the best you can afford. Personally, I'd probably go with the OEM wire set and the NGK plugs.

My 2001 Tiburon has the same problems your car has. My Check Engine light has been on now for approximately two years. It went off for two days after I had a new alternator installed but then the light came on again. My exhaust system is fine so the only thing left to do is try new plugs and cables. I've recently bought new spark plugs and spark plug cables so hopefully this will resolve the Check Engine light problem once I install them. I'll let you know. I will be using NGK spark plugs, not the Champion plugs that the manufacturer used (Champions are the cheapest plugs on the market).

The passenger-side power window still occasionally will not work for 15 or 20 minutes, but it eventually will start working again, usually within 20 minutes. Try using the passenger-side window button if the driver's-side button doesn't work. I looked into getting a new motor for the passenger-side window but estimates for this motor range from $300 - $500 and that doesn't include labor. But if your window will not work at all I don't see any other option than buying a new motor or trying to get a used one that still works from a junk yard.

I have the same issue.

I have a 2000 Hyundai Tiburon as well. I let me friend drive my car once i was away, and the next thing the check engine light was on. It is the Cylinder 1 missfire. I want to fix it myself, but i have very less knowledge on how to do so.

Could anyone please tell me what could have caused this missfire?

If I dont fix it soon, what will i be facing?

UPDATE:
I installed the new spark plugs and cables and the Check Engine light is still on. The car's running quieter and smoother now, though. The only other problem that I might have right now is worn shocks. The car makes a lot of noise when I hit a pothole, but I doubt this is responsible for the Check Engine light.
