its only when its idleing and it kind of sounds like its misfiring but not really. and it was pinging really bad before i changed the plugs but thats gone for the most part. you can faintly hear it at a certain rpm. i have a really bad exhaust leak at the manifold could this maybe have something to do with it?? i also cleaned the maf by the way. and it is a little bit rough when it idles too. any ideas?

 

Yea, you have to fix the known problem. Your timing may be over advancing due to your exhaust leak before the O2, since your AF's are automatically configured in these models. Did you have this problem before it leaked?

 

agreed, good time for headers

 

oh okay thats what i was thinkin. already bought some long tubes just gotta find the time to put them on. thanks
