I checked the cat with a digital thermometer and it showed it was working fine, also replaced the o2 made some difference. I will check the coil after I get the wires, I heard the secondary throttle vacuum thing can mess with these carbs too. Have any of you had this problem? I am hesitant to mess with the carb I have a toyota pick up also and that carb was a nightmare. Did a rebuild on it but it never ran close to how the weber 32/36 I replaced it with. I appreciate all the info guys ill keep you posted!
