Upon start up my '91 5.0 idles kind of funky as if there was a miss or a vacuum leak
At slow speeds it drives ok but not quite right until warmed up.
If I immediately shut off the motor and restart it runs just fine.
I've cleaned egr, iab, throttle body, new plugs, wires, distributor cap and rotor, new fuel filter,
replaced upper and lower manifold gaskets, all codes are 11.
This behavior appears to be temperature sensitive and is most notable during early morning
when temps are cooler. The "reboot" process seems to fix it....but is this a warning of
worse things to come or just a sign of old age? All replies welcome?
