catylic convertor

[hoosier]

i would like to know if a stopped up convertor will

cause my truck to be hard to start and to miss fire

No. A plugged converter will make it struggle at high rpm, wide throttle, will make it burn more gas and can contirbute to overheating and or pinging. It'll start and idle just fine.

 

Hard to start and misfire . . . depending on what year/engine your truck is I'd suspect distributor, injectors, plugs, vaccuum leaks.

I agree..best way I can describe it is a stumbling or loss of power on acceleration.
