My idle is fluttering. What could it be. Just changed the lift pump last night so I havent noticed it yet if it stopped. Im thinking maybe its the #1 fuel because I had this problem last year of it stalling when going in gears. Last weekend I just adjusted the bands and reverse is a ***** when going in. Stalls alot. Im thinking that #1 fuel is the cause because ive lost mileage also. Diese fuel addative doesnt seem to be helping since ive added a quite of bit to my last fill up. Any of you alaska guys know if they are still selling #2 fuel in Anchorage anywhere. I know we had this converstation last year. And only somebdoy in Fairbanks did. Could it be a sensor causing my fluttering idle?
