Have '72 1.7 with stock fuel injection. Car starts and idles fine when cold. Tach shows 850-1000rpm when cold. After the engine reaches operating temp it doesn't idle at all. I have to keep my foot on the accelerator at intersections or stop lights to keep the revs up so the engine doesn't die. I've set the idle with the adjustment screw with the engine hot and cold, but either it idles too high or hardly at all. Any suggestions on how to cure. Thanks for all responses.
