i have a 1992 b2200 fuel injected, and a while back it started running rough, only sometimes. It was bad to the point where once i got on the clutch it would cut out. When the problem starts it spits raw gas out of the exhaust. The smoke smells like unburned fuel. I took a look at my coolant and noticed the rad was empty and there was no coolant in the resevoir. I went ahead and changed the head gasket. When i finished the problem didnt change at all. I thought i had a stuck valve so i took the head back off, and swapped the gasket again, and i got another head from a parts truck. Same issue still it just spits raw gas out the exhaust in clouds of smoke. Before the problem started nothing was changed, nor was the timing changed. Im at a loss and cant figure out what the problem is, is there a sensor that determines the amount of fuel being sprayed into the cyclinders? maybe i have a faulty sensor or something on the intake. Any help is appreciated thanks Kiefer
