1970 Pontiac Catalina 400 V8 mileage: 150,000. The car will start very well when it is cold but as soon as it warms up it begins to sputter and miss and then dies. The choke is not sticking and I've replaced the coil. I also cleaned the carburetor.

Check for vacuum leaks, check the fuel pump pressure and flow. Check the vacuum advance plate in the distributor for wear.
