1991 camaro RS 3.1 V6 No throttle response ?

When the car first starts it runs fine and you can throttle it fine. As soon as the car reaches running temperature you can't give the car any gas or it will stall. It will only idle at operating temp. MAP and TPS were replaced along with Spark Plugs and Distributor cap. Any ideas? I am thinking an ignition problem. The computer came up "Electronic Spark Control"... is that the ignition control Module? Will vacuum leaks cause this problem? Intelligent responses only please!|||Sounds like a plugged catallitic converter to me disconnect exhaust at pipe before the converter and test drive it will be loud but see if it runs right if yes then repl cat.|||the control module verry well could be the problem,take it off they have a thin layer of grease between them and where they bolt up try a little piece of rubber between the two pieces and see if that doesnt help the problem bould be that its grounding out at running temp
