Thanks, maybe this explains my little rough idle when cold, also when the car is cold, seems like it is worse the leak

YES!!!! Fix it! I already went through it, it made my car run like **** because the leak was on the closest primary to the o2...

exhaust leaks can also be picked up as false knock, even with a lt4 KM, which will result in timing being pulled and lacking performance. i think this is part of my problem.
