Re: flashing check engine light
A blinking check engine light does mean a misfire is happening. It blinks to worn you that it is enough of a misfire to damage the catalyst. I have never seen a truck blink the check engine light and not set a misfire code. A simple tune up with plugs and wires pretty much always fixes that problem on these truck. When you say all those items were checked already what do you mean by checked? How were they checked? I have seen plenty of knock sensors fail but they don't cause isolated misfires. You might want to try a different technician to take your truck to .
