About a year ago my Dodge Ram v6 started missing shortly after starting
but settled down after a few minutes. Now it runs until the engine is
hot, starts missing and then stalls completely. When it cools it
repeats the behavior. Have replaced spark wires, dist cap, and coil to
no effect. Fuel pump has proper pressure. Mechanic I sometimes use has
no ideas. Any suggestions as to what to look for would be appreciated.
