My car has been backfiring since i got it really and the bumper around the exhaust is pretty sooty. It also smells nicely of petrol and isnt so economical. I've had a lot of people look at it and no one can seem to work it out, my last step is to take it to NI$$AN which i dont really want to do unless i have to.
I've just replaced the BOV to a Forge on (recirc) and this didnt seem to help. I havent been able to see if its still producing soot, but there is still banging..
If anyone has an idea of what it could be.. it'd be helpful. I've been assured the mixture in combustion is fine as well, which is why I changed the BOV as this is after the initial combustion process.. but anyways, advice please!!
