This is a problem, it needs to be at 56-60 to start and 61-65 at running/idle/acceleration. Any drop in pressure like that indicate lack of fuel flow. Your symptoms indicate a bad cpi/nut kit. Pull your upper plenum, look for signs of washing (where one side is cleaner than the other) If your passenger side is washed it's your CPI unit, if it's the driver's side then it's your nut kit. Though if you replace your CPI unit you should replace the nut kit as a matter of course because the lines get extremely brittle over time.) Once you do this get an immediate oil change. Why? Because more than likely you are dumping excess fuel (hence the gas smell) and a lot of it is ending up in the oil pan. This is not good as the gas washes the bearings and cylinder walls and you can loose your bearings. (Not a good thing)
