Re: Skipping Hummer h2
Mine did this the other day for the first time. Hasn't done it since. I got the feeling it was the tranny trying to shift in and out of OD. I gave it gas to make it down shift and it quit. Hasn't done it since. If yours is doing it at 55mph, maybe thats the same thing. My check engine light came on, but went back off the next time I started it. Since then the check engine light has come on every once in a while, but turns off soon after. Does the light need to be lit in order to get a code?
