I was sure I must have blown my head. But upon replacing my radiator, found it does not overheat at all, no water in oil, but seems like it is running on maybe 5 cylinders. Sometime when I fill up with fuel it runs perfect for a while, then back to stuttering. I am all but sure the sensors have fried. What is the cheapest way to verify the problem. Have done a computer test and established the sensors, just wondering about the head. Thank You

Check for dirty injectors and also the fuel pressure for a start.
