Ok so here is the deal. The last few months my camaro has seen many problems(as my cars always love to do when they know I am poor)and I just recently replaced the sparkplugs which I thought had fixed the problem(all my missing power came back, she is fast again)however today I noticed that in lower RPMs if I push the accelerator down too far she kinda "rumbles" from the undercarriage and there is a loud kinda popping noise that sounds like it's coming from right under the driver seat maybe a little back but it could be the exhaust. I thought it might be an exhaust issue but Im not sure. It's kinda bothering me, any ideas on what it could be and how much it might run to fix?

 

Engines dont like WOT at low rpms, does it do it at all in the high rpms or at idle?

 

Sounds like it could be a transmission mount to me. I know the LT1's have issues with breaking the stock ones, so people replace them with better mounts. Does it make a clunking sound when you start to accelerate hard and then it goes away once you're moving?

 

I haven't noticed the problem at idle or at higher RPMs though it does seem to me that she idles a little more roughly than I remember from when I bought her. She kinda does clunk if I accelerate hard if I shift and the RPMs are low and then stop out once the RPMs raise back up.
