my 95 cobra (specs in sig) has the really weird problem. every so often, like once a month or so, it just refuses to start. this problem just happens at random, and i have no idea why or what is causing the problem. it is getting fuel cause when i pull a plug you can smell gas, but the spark is just really really weak, and it will just crank and crank and not fire over. if i let the car sit for a few hours then go and try to crank it, it fires right up. I have no idea what the problem is and am hoping someone might have some ideas. This problem only happens very rarely and for no apparent reason.
