    Low idle problem

    I have been working on trying to get my truck tuned so i can actually drive it more, it was going better but now my idle is way low, i set my idle at 1000 to make tuning easier. Now my truck idles really low and does not respond to VCM controls in the scanner. The odd thing is i can hold 2nd gear going up a hill at 450 RPM!!

    You don't have to take it out of your tune.

    Do you have anymore details on the truck? Why is the MAF table zeroed out? Nothing else is in SD mode from what I can tell. The lower VE table numbers are really messed up.
