erm ok..thanks

what about that horrible stench?

[180fan]

check your mafs. it's probably allowing for alot of unspent gas to fly through. do the fumes sting your eyes and such?

Check to make sure your fuel injectors aren't leaking, although that would smell whenever the car was on, not just at idle.

well it only has that smell when i rev it high

my car started running really rich to where it coated the plugs a few days after I hooked a nitrous kit up to it. it would backfire when I ran the rpms up very high and let go of the gas. turns out the fuel pressure regulator hose had fallen off when when I hook the nitrous kit up through it. make sure your regulators working.
