1985 4X4 EFI. The engine has a strong surge in the range of 1500-2700
rpm. Simply won’t idle at a stable speed in that range. I have
checked most of the obvious things–air vane box, throttle position
sensor, EGR, and so on. I can’t pin down the problem. Any
suggestions? Won’t pass state inspection because there is an
emissions test ate 2500.
Also, checking the ignition timing calls for shorting a "T" connector,
but none of my books–including the factory shop manual, are telling
me where or what that is. Can anyone advise?
Thanks!
