for those with lincoln's that are running rough i'm having the same problem. Here is what i've noticed, if you start to smell gas look under your car to see if there is fuel coming out of the exhaust system. Look just in front of the rear tires under the car at the mufflers and you will see Fuel coming out in a steady stream. Also at this point it has collected in your air intake system and may even be in your air filter.

Can you elaborate on that? I've never heard of raw gas coming out of an exhaust system. What exactly would cause this?

If raw fuel is coming out of the exhaust, the only cause could be that there is no spark getting to one of the plugs (or more) on that bank, if there was spark getting to all cyclinders then there would be no raw gas. If the injector was getting a constant spray signal, at least it would burn it up on every fire sequence, would run rough and smell really bad, possibly black smoke coming out the tail pipe. I say either fouled plug, bad injector (injector or signal to injector) bad wire (wire or coil), or a combination of several of these. Usually you can pull the plug and see which cylinder is having a problem by looking at the sparkplug, after it has ran for less than a minute. Start at the bank from where the fuel is pouring out of the exhaust system.
