Ever since I put the super comp. hooker headers on my 99 z28 M6, I have been noticing blue smoke and a really strong gasoline smell, which gas is at like 4.50 right now so no one has gas to waste. I have heard the engine may need to be overhauled, does anyone have any cheaper solutions about this? Also at idle it is rough sometime seems like it wants to cut off also it backfires sometimes while driving it. Thanks for any response.

You might have a broken plug or plugs that's not firing and raw fuel is what your smelling. If all the plugs check out ok, then like mentioned above you need a tune cause it's running rich. The blue smoke is probably just the new burning off of the headers.
