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..
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.
