ok..I had this problem when i got the car (when i come to a stop the rpm's drop off and it dies) it an automatic 1.6 vtech sohc.. I replaced the coil... dis.cap and rotor and plug and wires and put some injector cleaner in the tank, and its still doing it.. i'm gonna try the fuel filter but I don't really think its that for some reason... and there isn't a engine light on --- maybe the ICM ???
