Hey guys,
The past few times i have driven my car i have been noticing that there is a strong smell of raw fuel in the cabin when the blower is on and sitting at the stop light. Here are the things i have been noticing:

-Raw fuel smell in cabin when at a stop light (when the blower is on)
-Lots of grey smoke at start-up and light smoke when at operating temp.
-Terrible gas mileage (170/tank, when i was averaging around 350 before)

-protuned by Tim of PDX tuning

So what do you think it is? Maybe a leaky injector? Im trying to get an idea before i start tearing into it.

Thanks in advance

Let's start with the obvious: is the light smoke bluish, or whitish? Bluish == burning oil, possibly the piston rings. Whitish == coolant, busted head gasket.

ummm...how about a loose fuel line.

umm, i dont think so. The smoke is GREY which usually means unburnt fuel. I am not burning oil nor coolant.

Anyone else have some helpful suggestions?

Yeah I have a suggestion, use the search button this is a extremely common problem when it gets cold.
Hell there is even a TSB about it.

350???? How do you get 350! I get 230 max and im all stock! I dont dog it either

Yeah I had the cabin fuel smell last winter, but it eventually goes away. In my case it only did it on extremely cold days (like < 20 degrees) after the car was sitting for awhile. It has to do with a faulty rubber seal in the fuel line IIRC. It will be fixed for free at your dealership since there was a TSB on it.

As far as the grey smoke, Im not sure about that. I didnt have that issue. It may not be related to the fuel smell issue. So get the line fixed first then see if the smoke goes away.

You said grey smoke at STARTUP, followed by LIGHT smoke at op temp. Sorry if what I wrote wasn't what you wanted to hear.

Thanks for a straight response. I'll look into this.

tsb does not = recall

thats means your dealership will most likely want you to pay for the 600-700 repair. ive been meaning to send SOA an email about this. I saw the actual line and gas seriously squirts out of it. makes me a little nervous...
