So I've been doing some great reading from previous posts to try and fix this really annoying hesitation problem on my 87 60 series. The past few days I've been trying to isolate some emission components using hemostats which seems to work for most of the day but eventually the rig starts to act like its starving for fuel. What the heck could cause this thing to run like a top with plenty of power and then turn it into a hesitating stumbling pile of pooh? My friend the PO reminded me that the dealership told him there was an exhaust leak and the exhaust manifold gasket might need to be replaced. Could this be causing some vacuum pressure problems? I'm not a mechanic so this is becoming more and more frustrating for me. Any ideas?
