I changed my plugs and made sure I had the right gap, but I am using a lot of fuel and the car is pausing when I go to excelerate. I am also smelling a strong gas odor

Try the fuel pressure regulator. Pull the vacuum line and if it smells of gas, replace the regulator.

Sounds like you have a fuel mixture problem. Usually there is a sticker in the engine compartment that gives the spark plug gap. Unless the gap is way off it will not cause this kind of problem.. Are the plugs carbon fouled?

you should not have to remove the fuel rail to fix your plugs. Find your distributor cap (kinda looks like an octopus with wires going to each piston at the head. Trace these wires to find your plugs. Only do ONE at a time to make sure you keep the correct firing order. Remove the spark plug wire from the plug (it should just pull off ... though you might have to wiggle it back and forth a little bit to get it to come off). Use a spark-plug socket wrench to remove the plug. Before you put your new plug in, make sure that it is gapped correctly (the little metal L is the right spacing from the electrode). To do this, check your user's manual for the correct spacing and get yourself a "gap tool" of the correct size from your local auto-parts store (they can describe exactly how to use it -- and they might even help you gap your plugs before you leave the store). Once you have the plugs all set to go, put it back into the engine with your spark-plug socket wrench. DO NOT FORCE IT -- if the plug is not lined up right, it will get stuck, remove it and try again. Forcing a spark plug into your engine will damage the engine and cost you a lot in repairs -- take your time and be gentle with it. Also, do not over-tighten the plug into the engine as this will also cause damage and be hard to fix. If you have questions about how much to tighten it, ask the auto-parts dealer when you are buying the gap tool ... this can save you a LOT of hassle in the long run. When you have the spark plug where it is supposed to be, and tightened properly, put the wire back on it and that one is done.
Once your first plug is done, move on to the second, and third, etc. Do only one plug at a time so you don't lose track of which wire goes to which plug as this can also cause you a lot of hassle. Once all of the plugs are gapped and installed you should be good to go :-)

Check to be sure they are in the right firing order.
Check the gap on the plugs.

white smoke is probably steam,do a compression test on that cylinder,and check for any evidence of a blown head gasket,(oil in water or water in oil)

i was wondering if you made sure that the gap on the plugs was correct for your vehicle it is different from car to car. I had that same problem of course mine was doing that right off the bat. so you never know. but again another possibility to check.

i have 87 nissan pick and wont start and cluth is loose and leak under neat smell like gas

You are correct in saying the gap. Call a suzuki dealer, ask for service and as what the gap should be. Your problem is more than likely not having set the gap. Before you change that gap, if you can, measure what is now vs/what it should be. You will need a feeler gauge. Grainger sells the, so des NAPA.

change plugs (make sure gap is right), plug wires, coil (if applicable) make sure you are using good fuel i rec'''d conoco gas...
if you had work recently done then i would also trace it back to that.

did he gap the plugs properly? sulfur smell comes from excess fuel being dumped into the exhaust (catalytic converter). Could be the coil, or improperly gapped plugs. If the wires were out of order, there would be a misfire.
