'74 2.0 with .010 oversize cylinders, original Jetronic fuel injection intact and works great 95% of the time. However, engine idles very slowly (almost off the bottom of the tach scale) and will eventually stall unless throttle is "goosed". Condition only occurs in high ambient temps after 15-20 minutes driving. Then hard to start without a bit of throttle, but starts fine with that little bit of throttle, so I don't think it's fuel vaporization. (Fuel pump has been moved forward and fuel lines are all SS.)

Runs normally otherwise. Cylinder head temp sensor? Idle adjustment? What? Any ideas would be appreciated.
