My first thought is that you have a burnt distributor rotor or cap,remove the cap and look for small thin lines that have a rainbow effect around the edges of the lines.If all looks good here,you might consider looking closer at the cat converter,most times when they are stopped up you will hear a sound i describe as a hiss or vacuum cleaner sound,hope this helps
