I agree with ztar1462, but also check for the slightest vacuum leak, pinches or cuts, also check for the proper routing of the ignition wires, yes this can cause problems as well.
I would also scan the vehicles computer and then check the EVAP system complete, the purge solenoid, canister and the vapor lines as well.

Sounds like you need to replace the converter. I would do a complete tune up for good measure - i.e. New plugs, wires, air filter and run a fuel system cleaner in it. If the check engine light is on as well get that checked out too. Hope this helps
