I have 1981 1600 crossflow. I alluded to this problem in my last post, but its getting worse.

My engine revs drop when the car is warm/hot and at idle. The car starts fine. And when driving she is OK. But when stopped in traffic, or like tonight just sat in the garage, the revs suddenly drop and she stalls.

Give her a minute and she will start but runs roughly. Give it some welly and she is OK higher up the rev range. But ill return to idle, and then die quite quickly.

The choke opens properly and I have not changed the settings other than take the heavy air filter of a couple of years ago. Valve clearances are fine and she has an electronic distributor. I also note that if at idle, the revs drop when the the lights or heater etc s turned on.

Any ideas?
