True Bernd, and I actually looked the 'idle adjustment' screw on the spring
plate, which basically acted like a door stopper and allows the throttle
blades to spring back and close the bores, just enough to keep idle down and
let the truck get enough air flow to keep running. I really though about
this, but couldnt justify messing with it/adjusting the blades open more at
idle, since I have never messed with this adjustment screw. The one thing
that still gets me though, my truck has been idling higher than normal since
all this started. It always idles and 650-700rpms, and throughout this
ordeal, the truck has idled at 900rpms-sometimes even 1000rpms. When the
truck dies is when the rpms actually drop back down to the 700 range, then
it cuts out and dies. Thankfully it restarts. Like I said though, it has ran
great the last two days. Is there a given factory spec. measurement on how
far in/out the adjustment screw should be at.......other than saying the
truck is supposed to idle at 600-650rpms. I mean I could open/close and keep
playing with this adjustment screw, but I dont want to screw anything up
more if there is no need to mess with the screw. Oddly enough also, the
truck runs considerably worse when the MSD ignition is unplugged and the
stock ignition is put back to work. getting strange isnt it?
