So my car had the original exhaust on it and I kept getting CEL for poor catalyst flow and a/f ratio sensors so I replaced the upper cat and the lower connecting pipe that holds the down stream sensor before the second cat both sensors are brand new I put brand new properly gapped spark plugs I’ve put a brand new air filter pulled the intake off and cleaned the throttle body no codes are running since I’ve replaced the exhaust but the cat is now glowing slightly red and only after I drive it for a small drive and my innova 5130 code reader keeps blinking Eva and the cat light only blinks when the cat seems to really warm up any ideas of what could be next ?
