blazer surging when going uphill
Hey all having some issues with the 99 I just a motor in. It is surging while going uphill I can watch the tach jump back and forth from 1500-1800-2000ish rpm. Seems to do it between 45-55 mph. I have no vacuum line diagram so I'm unsure if its vacuum related. Its a 99 S10 Blazer 4x4 LT
