![]() If it smells raw then you have a leak, under the hood or elsewhere.. if it smells burned, then your running rich.

![]() If it's an outright fuel leak, that should be easy to spot since the system is highly pressurized.
The other 2 usual suspects are 1. The hose that runs into the charcoal canister. This tends to detach and then the gas tank fumes get vented up front. It's a small black box on the passenger side of the enginebay to the right of the radiator shroud. It has 2 bulbs on top (or two openings if the bulbs have fallen off) and a hose running to it. 2. The little shroud around the filler neck detaches after a while and then when you filler up, some gas pours past the seal into the inner rear 1/4 panel. This causes a ridiculous stink. If the engine was that off, you'd have a check engine light and some codes stored in the computer. Just check the exhaust. If it's clear, you are ok. If it's grey or black, your're running rich.

![]() I had the same problem with my car and it turned out to be a leaky fuel injector, if all else fails check ur injectors while or right after your cars been runnning just look for a wet injector or a fuel puddle on your manifold.
