nope because i keep my car very very very clean like **** obssesive and ive never seen anything that would make me think an exhaust leak. but ill take his advice and put it on the lift while running and double check.

 

Or you can **** on the coils



Klatinn once recommended to get someone to place their hand over most of the tailpipe. If the AFR drops, then it's an exhuast leak. It runs lean because it draws air into the stream of gas thats picked up by the O2, build a little back pressure until it quits sucking by blocking the flow somewhat.

 

WTF is this supposed to mean?

If there was a leak at the o2 housing to downpipe connection, it tends to blow up to vent in the hood thus causing soot on the valve cover...

 

then i dont have a leak there cause i dont get soot anywhere. but im still going to check today on the lift.
