my 87k5 has an intermittent fuel problem (i think). i will be driving along and the engine just cuts out, press the gas and nothing. but it does kick back in. sometimes the engine stalls completely and other times it does not. i replaced the fuel filter. checked the wires up to the fuel tank, but have not looked inside the tank yet. replaced the dist cap, rotor, wires and plugs. they were all corroded. ran great after that. thought that fixed it, but then it did it again yesterday (engine cut out, stalled). any ideas? have blown the ecm fuse a few times while this happened too. and my gas gauge, like everyone elses, jumps all over the place. sorry for the novel, but this is driving me up the wall.
