    Rough starting OX66

    Does anyone know if a 2000' change in altitude would cause my 2003 OX66 to have a really hard time starting? Went to Clear Lake and it ran like crap.

    Not sure about altitude.


    Check your lift pumps.

    Altitude will affect any motor till the computer makes changes but still will change the performance. Also your low pressure pumps might need new diaphragms super easy to change. Also might need to clean the 02 sensor which is super easy to.
