Hey Captain,

I have the same identical symptoms on my SRT. I just took apart the TB gasket, intake and checked for leaks, loose bolts, hoses, etc. The gasket was in perfect condition, so for me this was not the cause. I've had these symptoms since the car was stock and I now have the DCAI, tune and SC pulley. IC Pump was just replaced 2 months ago.

I recently added tighed1's DIY belt wrap mod and will wait for some good weather before taking the car out for a spin. Not sure if this will help as the car was doing this in stock form, but its worth a shot.

Keep us posted on any updates and I will do the same.
