My '73 2.0 idles beautifully when cold - right at 950-1,000 rpm. Once hot however it idles way to fast - around 2,000-2500 rpm. It runs great other than that. Any suggestions on troubleshooting?

It could be the dizzy( as mentioned)
. It can also be an air leak. Usually the air leak comes from the phenolic spacer between the intake runners and the head. The way you check is to let the car cool, fire it up and spray carb. Cleaner in that area. If the idle rises after you spray, thats where your leak is. Spray sparingly so you dont saturate the area . More than likely the spacer is cracked or the gaskets need to be replaced. Easy job. |
