Exhaust/Vacuum Leaks?
 

Hi all,

I noticed the other day what smelled to be an exhaust leak when I started up the car. I looked around the DP area and saw some whiffs of smoke. There also seems to be a bit of stumble or hesitation with the throttle when the car is cold, which is kind of hard to hear in the video.

The car is a '93 with 50k miles original and stock minus a DP, bonez high flow cat. All emissions in place.

Could it be the original paper LIM going causing the stumble/vacuuum leak? Should I recheck the DP nuts and studs torque for an exhaust leak? I did install the DP a few years ago and reused the turbo to DP gasket.

Thanks for any/all help!
