Running on three cylinders...

I have a busted spark plug that I cannot remove to replace... I live in a small town and have been driving on only three good spark plugs for a few weeks now... But I need to make a 3 hour drive tomorrow, is this safe for my car? If you have advise for me can you please send your response to [email protected]? Thanks!

Is it broken? Plus it not good to drive the car like that for a long time

Well, lloks liek I'm a week late but to answer your question I'd say no. Did you do it?

If you continue to drive like that, the unburn gas-air mixture could burst to fire in your catalytic converter, where the temperature could be very high. If your catalytic converter is destroyed, it will cost you >$1000 to repair.
