Bad Idle Trouble

[posied88]

I have somewhat of the same problem. It idles around 1000 and then drops to about 500.It does almost anytime though. When I'm at a light I sometimes have to give it gas or else it will die. I dont know what it is but I recently installed an off-road H-pipe, and it never had that problem before. I thoght it was my cam at first because it did it before but very little like when it was hot or cold. I also thought it may be my timing.maybe someone out there can help me with a solution or something.
Thanks.
