[QUOTE="ib_604, post: 6641175, member: 44160"] Hey guys, i know, i know, your laughing, bad gas mileage in a cobra? with record high gas prices? lol but seriously.... My car was in storage, for about 6 months. I did a few things: -changed out spark plugs to NGK Iridium's -changed badly plugged fuel filter -cleaned intake filter -installed fuel PSI guage before i stored the car i was getting about 350-380KMS/215-240MILES per tank. I got the car back on the road....the first tank only lasted about 220KMS/135MILES thought maybe it was bad gas, so i got some Gunk injector cleaner, and a fresh tank, and still was getting shit mileage... My fuel PSI is usually between 30-40... My QUESTION, (after searching) is, what could be causing this? I am thinking a few different things, but i am not very knowledgeable... 1-need a re-tune because if the new fuel filter, maybe its working too well? 2-o2 sensors need to be cleaned? 3-new spark plugs gapped wrong? (i went with the norm off the forum, i think .037) PLEASE give me your ideas!! This is annoying as hell....THANK YOU! [/QUOTE]
