SR exhaust smells wierd

[drft911]

Ok lately the exhaust from my sr has been smeling wierd, no i dont go around smeling Co2 just that lately its been smelling stong that i stings your eyes for example when i hit the gas while backing up smells like an improper fuel mixture. so i disconnect the iacv no change in idle then tps still no change in idle the i check the exaust and its that smell but more stonger. what is wrong tps or iacv?

^ was saying the same thing, but wonder....my friend has a b17 integra..and he had a walbro 255. and his car would run really rich and smell bad..well he bought a fuel pressure regulator..and it fixed everything..

hope it helps
