My 94 Civic ex will turn over crank and stop immediatly, sometimes it will just turn over, but every once in a great blue moon it cranks right back up, until i actually need it for important things, like how i missed work today, i checked the fuel filter it was fine, so i assume the pump is too since its before the filter, now i sprayed some throttle boddy cleaner stuff (cousin said it would clean my idoler control valve or something from reving up annd down) and it would usually crank has anyone ran into this problem? can i get some help i mean i seriouslly need to know whats wrong with it
