I need help diagnosing problem with motor underload ,it cuts off and notice cat

Thank you for inquiring,base on the symptom the vehicle seems to be dumping excessive amount of fuel. I would suggest you go to our website at euromotorcarsofmemphis.com, & schedule an appointment so we can diagnose the vehicle to determine cause. Thank you.

cut the converter off and replace it if you want. the reason why is its stopped up thats y its glowing red cause there is no exaust coming out of your muffler..
