Ok, here's my situation...

Recently, I changed my spark plugs and wires. My car was running ok before I changed the plugs and wires, but they hadn't been changed in 50,000 miles since I got the car so I did it for preventative maintenance. While I was changing the plugs, I stripped one and kinda forced it and I may have overtighened it to get it in. So I bought a spark plug tester so see if it was ok. It was firing and seemed good. I started the engine and let it run for about 20min and took it for a test drive and couldn't figure out why it was running so rough. Afterwards, I realized that I didn't have one of the spark plugs in the back in! Don't ask, I thought I had them all in. Anyway, after putting the plug in and checking everything again, it runs better, but I am still getting a really rough idle. While driving with the plug out, could I have clogged the cat converter or fuel filter? What else could have gone wrong here?

Thanks for any help anyone can give....I really don't want to take it to a dealer and get raped for hunreds of dollars.

If you jammed one in, you may be losing compression on that cylinder.

Hopefully though you just have a couple plug wires reversed with each other, chek them first.

This sounds familiar..

Did you strip the plug, or the threads in the head?

Only one thread comes to mind reading this.

Yes, cross threaded the plug...why did you link that other post to mind?

Because you drove with the plug out...real bad idea.

I know it is a bad idea, but what could have happened to the engine by doing this?

That's funny GAlover. I bet you are on of those people that drives around with their seat back and playing Nelly on your Audiovox sound system thinking you are Vin Diesel. Putting a loud exhaust on your car does not make it a Porche, cool guy.

WTF??? He was just referring to a thread we had a while ago of a genious that bought 5 plugs for his 6 cyl car...

Calm yourself. You sound pretty experienced with nelly, audiovox and fantasies of vin diesel. Creepy.

Well, I'll take a free stab that you could take at this problem. The car might have tried to compensate for the dead cylinder and could still be trying to do that. You might want to try pulling the negative battery terminal to reset the pcm, it might help. [2 cents]
