poor idle

I have a 1995 Eclipse that when it is cold it will idle fine. Then when it starts to warm up it will start to mis-fire. As soon as you increase the engine speed the mis-fire goes away. The car had problem code for the EGR valve and so that was replace and cleared up that problem. It had new NGK plugs installed.
Any help would be great

Did you check your plug wires too?

Also you should put your model eclipse in your signature along with any mods just for help referance and welcome to AF :bigthumb:

what did you gap your plugs?

I gaped the plugs at .48

search...

One more thing to add is that the timing belt was replaced 5000 miles ago and it did not seem to idle rough then.

Welcome to the club.:frown:

Just to add to the information. When you put load on the engine such as the turning on the the A/C the idle smooths out

Ngks should be gapped at .028 but thats for turbos :S. Still I don't thinkg it should be at .48
If you search "plug gap" in the performance section you will find the thread on that one.

Factory gap on a 2gnt is .44 Have you checked for a vacuum leak?
