ok so once i start my 98 z24 with just an cat-back system that came with it, with no warm up i would drive the car like maybe 200ft (from parking lot to traffic light which is 9 out of 10 red ) the idle would just drop when i take off to the point were the car would just suddenly bog down then ill hit the clutch then give it some gas then let of then pell out (accidently) then it'll run normal till i leave the car off for like 4 to 5 hours..on thing i heard but dont know if its the problem solver to the situation, but i have one of those gas caps with the lock and i dont know if it has something to do with the pressurization of the gas cap or what am confused and thats why am here so anything would be helpful

wow no one can help meeee whhhyyyy
