Ok here is my problem guys. When my car is cold it kinda idles with a shudder. Its not like a miss but it has a shudder to it. My O2's were bad about a year ago and my opti also went. Could these things going bad have screwed up my plugs and would bad plugs cause this. There is no hesitation at all when I step on it and the shudder goes away with a little throttle. Any help would be great.

 

mine does the same thing. in the morning it shakes, but when it gets a littel warmer like 5 min idling it will not shake. When i am driving no problems. just mornings.

what could it be?

 

Come on, nobody knows if plugs and wires could cause this????

 

Does anybody know the answer??????? Anybody? Anybody??? (From Feris Beuler or however thats spelled.)
