Hi there, after my header install I am experiencing intermittent rough idle at a stop. My installation was an Edelbrock TES and a single universal 3" Carsound cat joined to a stock muffler. I replaced all plugs and the 02 sensor. I did manage to whack the tip off my corroded connectioned knock sensor (has been ordered) In the meantime I am driving the car. thx

check your plug wires. ill garrrunnteeee you burnt one or didnt connect it all the way.

I'll bet it may be a burnt wire as well. I have put 1-3/4" headers on and burnt up two of my wires. I realize it gets hot under there, but didn't realize that hot. Anyhow after replacing all my wires (boots were all burnt through) and then putting on spark plug insulation, it idles much better.
