after sitting a few hours my del sol is a pain in the *** to start its sputters and misses til it finally starts up. then i could start it fine after running within 2-3 hours. my new spark plugs had a dry black sooty texture at the top. bad air filter maybe? or fuel filter? im thinking im not getting enough air in the mixture and too much gas and maybe drowning out the spark? also ive been getting crappy milelage lately

 

yeah sounds way rich, fuel pressure gauge?
