First I hope this is the right forum........Anyone have any idea what the popping/ticking noise is? Coming from the rear of the car near the exhaust (under trunk). A few weeks ago I had the exhaust leaks welded. It happens when the car gets hot.

hmm mine made a similar noise it was a leak where the pipe connects to the muffler it was my clamp, but since you say yours is welded I don't know get underneath there with the car running and see if you can feel any hot air coming out around your wleds.

 

Should I scan the car?

 

If there was an exhaust leak before the 02 sensors, a scan may turn something up. But if it is that far back by the catback, then your best best is to get under there and see if you can find it.

 

Well I scanned it and nothing showed up....However when the car was idling it was making weird noises and the car started idling at 2000 rpm...WTF

 

i would just do like everyone else said to figure that one out...just get under there and see where its comin from...dont think the idle has anything to do with the noise tho

 

Well...a few weeks ago I lost a spark plug.....after replacing it the ticking sound is gone

 

Thats happened a few times on here before. At least it was sort of an easy fix.
