Here's the rundown. Put a new primary o2 in last night as the old was throwing codes. This morning, car starts up fine, I get a little bit down the road and notice a ticking noise. I continue to drive and notice that the noise is only present under load. The noise is independent of engine speed. If you let off the gas for a second then press it again and its under load it will tick fast then slow down into a rhythmic tick. Any ideas what this might be???

 

car bomb
axle joints
wheel bearing

 

Hrm, hoping it's the car bomb!
I do have 1 cv boot with a slice in it, haven't got around to pulling it and exchanging it since it's still under warranty. Seems like it is coming from the opposite side though, I will check it out. Thanks!
