ok so i have a 2004 Monte Carlo SS 3.8L not supercharged, having and intermitten cutting out, some kind of backfire, and stalling under load. the car idles just fine and never have problem starting it. it also throws no codes or check engine light. this is very aggrivating any help would be very useful and appreciated.

 

Check to see if your catalytic converter is plugged you can do a quick check by running the car and taking a look underneath to see if it's glowing red. Or take it to a garage.
Could also be plugs and or wires

 

thank you. any input is very helpful as i am completely stumped. i have changed the plugs and wires and did not help. would the converter make it run like that all the time?
