    Ran perfectly for 5000. Chk Eng light off and on. Idle too high in Pk. On cruise intermediate misses, almost like it’s starving for fuel/oxygen. I am sure it’s minor. Thank you very much.

    When the check engine light gets turned on, the truck's computer will store a code that will give details about the reason if was triggered. As mentioned, an OBDII reader can read (and clear) any stored CEL codes in the ECU. If you don't have access to a code reader like this, local auto parts stores like Autozone or O'Rielly's have a tool they can plug into the ODBII port on your truck to read the code(s). This is a free service.

    If we know what the code that triggered your CEL is, we can give you advice on what is wrong and what you'll have to do to fix it.

    not all performance issues throw codes. the idle is always higher in park around 700. and does the miss happen only when in cruise control or at a steady highway speed?
