Ok so I have a leak in my flex pipe and it feels like a loss of power at the top of the gear and when I watch the air to fuel gauge it starts to lean out towards the end do you think it's a possiblity that the leak could cause these simptoms?

 

The A/F guage is reading lean because it is downstream of the flex pipe which is probably sucking in some extra O2 giving u a false reading.

 

Does it sound like crap? Mine did when I had a leak. lol

 

yeah. it does...im having a flex put in right now. as im typing but yeah some techs at my work said that would cause all that
