Car shaking
Yesterday I took the Camaro out of the garage for a little drive. When I came to a stop light it seemed like the car would vibrate a little more than usual and then it would settle back down. When I would get on the throttle the exhaust started crackling. I put on some American Racing Headers about 150 - 200 miles ago, but during those miles it never crackled before.
I still have not gotten around to getting the car tuned yet. Any ideas on what is causing this? I understand the exhaust popping on when slowing down, but never expected it to pop while getting on the throttle. 2011 Camaro SS L99 ARH 1 7/8 CAI w/scoop RX CC 3025 miles

From my understanding headers won't make you go lean, but a cold air intake would. However, from what I have read Cold Air Inductions wont screw up your AFR.

True, but while sitting idle at a stop sometimes the engine will drop into 4 cyl mode or under a light load and this can cause some vibration as well as exhaust note / tone changes which with a factory exhaust is not as noticeable. The range device makes the engine stay in 8 cyl mode ... always and does not mess with the factory tune.

I guess I'm fine with the popping, but I just thought it was unusual that it just started as opposed to when I put them on 200 miles ago. Definitely scared the crap out of me because i wasn't expecting it. Thought I hit something at first.

Thanks for the offer, but I am planning on tunning it sometime this year. I have stuff going on right now...basement got some water in it, wifes pregnant...yada yada yada. Unfortunately the nearest dyno tuner is about 2 1/2 hours away.
