DESMAF at high speeds
Around town everything seems ok but when at freeway speeds DESMAF is at .22 and acts like cruise control not letting the RPM come down. DESMAF doesn't come down until after coming to a stop. Is there anything with ISC that relates to MPH?

Re: DESMAF at high speeds
Dashpot was the problem. For some reason I messed with the higher rows and didn’t know what I was doing. I put it back to original and all is good now.
