Re: RPM surge? 2003 H2
I am having the same issue on my 06 H2. I had the garage clean the throttle body and it went away for a week or so. I also averaged a little more than 2mpg better. Since then the surging comes and goes. I also have went down about 1mpg less but still averaging over 1 mpg better than before the throttle body cleaning.
