Exhaust gas smell
 

Anybody experience the smell of exhaust fumes when coming to a traffic standstill? The weird thing is it doesn't smell during idle and I can't smell it during cruising or hard driving but always when I come to a slow stop from cruising or boosting when I can smell the fumes. Where could this be coming from?? https://honda-tech.com/forums/images/smilies/mad.gif I'm afraid I have a leak somewhere
