I have a 1987 Mazda B2600 4x4 extended cab and I am having problems with it it starts fine and smokes a little for a few min the when i start driving it it will go for a little less than a mile and then it will start lunging really bad like it is stalling out while im driving at speed and then it will eventually just die when i give it gas while it is doing this it cuts off even faster but i can wait a few min and it will start and go for about the same distance again and do the same thing what could be wrong with it I have changed the pluggs and plugg wires and the pcv valve and one of the catalytic converters and the fuel filter and the oil and oil filter what else could be the problem I need some help!!! I have no clue what else it could be someone told me that it may be the ignition control module but Im not sure if that is the problem or not if anyone can help please do it would be greatly appreciated THANKS CLAY!!!!!!!!!!!!!
