Hey,
I'm new to this board but been browsing threw this web board for a long time. I was wondering if you could help me with this bad smell coming from my car. It smells like carbon dioxide or something. I asked a friend and he told me it might be my Fuel Map Sensor. Do you guys have any idea what may be wrong?
Here's a parts list of my car if it helps..
B18c Block, ITR Valve Train, w/ Ported and Polished Head, Injectors, JDM ITR 4into1 Header,Pistons, Cams, Intake Manifold, Custom IceMan Short Ram Intake, 5-Zigen Fireball Catback, Spoon Cam Gears, Throttle Body, and Head Gasket.

Any opinions would be well appreciated. Thanks.
Nic
